How To Calculate Percentage?

The simplest way to calculate percentage is to divide the given amount by the total amount and then multiplying the answer by 100 to get the percentage of the given amount with respect to the total amount.

The equation can be put up as follows:
(Given amount/ Total amount) x100            

For example if John scores 60 out of 75 in mathematics we can find the percentage of his marks by dividing 60 by 75 which comes to be 0.8 and then multiplying it by 100 which gives us the percentage of his marks in math which is 80%.
(60/75) x 100 = 80%

When there are a number of given amounts (variables) and we have to find their individual percentages then we have to add the given amounts to determine the total amount after which by the above mentioned procedure we can easily find the individual percentages by dividing each given amount by the total amount and then multiplying it by 100.

Percentage questions are often worded in different ways like how much is x% of y (80% of 75). Using the above example we can find the answer by multiplying 75 by 80 and then dividing the amount by 100 to find the answer which is 60. To calculate percentage increase or decrease between two numbers just subtract the smaller number from the greater and then divide the answer by the original one and then multiply it by 100 to determine the percentage increase or decrease. For example to calculate the percentage increase from 20 to 30 we subtract 20 from 30 and then divide the number obtained which is 10 by the original number which is 20 and then multiply the obtained number which is 0.5 by 100 to get the percentage increase which is 50%.

Let's take for example a maths score,

you got 35 marks on a paper. The paper is out of 45. So..

35 divided by 45 = 0.7777777
x100 = 70%

simple

here's another one



16 marks out of 20

16 divided by 20 x100 = 80%

16/20x100
a/bx100

hope this helps :)

For example..

20 people out of a class of 40 got full marks in a test. Write out the percentage of the class who got full marks in the test.

20 divide by 40 times by 100
(20/40*100)
= 50

So 50% of the class got full marks in a test.

Of course there is a mathematical formula to calculate percentage and it was written in previous answers. But I want to show how one can fast calculate percentage in mind. For the begining one can always calculate 10% of begining number (for exmaple x  (this is easy because it is y=x/10, by y I denote 10% of x). And next one can calculate 1% of begining  number (denote by z) - z=x/100, or z=y/10.
And now one can calculte any percentage of number.
For exmaple:
We want to know - 23% of 123:
10% is 12.3
1% is 1.23
so

23%=10% +10% +1% +1% +1%=12.3+ 12.3 +1.23 +1.23 +1.23
        =24.6 +3.69 =28.29


PS.
Sorry for my english :-((

the way to calculate the percentage is:

p = B * R

P is part,
B is base,
R is rate.

so we change the position to find rate..

R = P/B or Rate = Part divide by base..

e.g.
part is 10, base is 100, find rate..

so use the formula..

R = P/B

R= 10/100
   10%

Regardin stitches answer on 3 jan 2007

the way to calculate the percentage is:

p = t/n

P is percentage
T is total value
N is no of percentage.

so we change the position to find rate..


e.g.
total value is 381,no of percentage is 5

so use the formula..

p= T/N

p=381/5

p=76.2%

In education point like percentage of total marks earned:your mark/total marks and multiple it 100 ie; your mark-400 total mark 500 :400/500:.80  x 100.

In business point that is profit percentages total profit earned/total sales and multiply it 100 ie, your profit :20000 and total sales 200000.00
20000/200000: .10 x 100:10%

BY THE RATIO FARMULA
   If you got 'a' marks out of 'b'
then %=x

     x/100=a/b

e.g.
    If you got 20 marks out of 50
then %=x


    x/100=20/50

   then x=40    i.e 40%

the best way to calculate percentage is use that formula

(the points which you have/ total points)*100

For example that you scored 500 out of 750
So the points which u have is 500
Total points is 750

Therefore, your percentage will be:
(500/750)*100 =

percentage is defined as what you get in how much according to 100.if a person find 1000 tickets & he wants to sell 5% of that then he has to multi 1000 with 5 & again divide it by 100.so he has to sell 50 tickets.this is an example to define the percentage.

Percentage refers to a number in terms of 'hundred'. In other words, percentage means 'parts per hundred'. It is calculated by using three steps:
1. Note the value of the number given, for which you have to calculate the percentage. Say, it is 500.
2. Note the value of the percentage to be calculated, say, 50 percentage of 500. percentage is normally indicated by this sign: %
3. Now, the final step: to calculate 50% of 500, divide 50 by 100, and multiply this by 500. The formula used is this:
= 50∕100 × 500
= 50 × 5
= 250
Therefore, 50% of 500 is equal to 250.
This is a simple method to calculate percentage.

Turn your percentage into a decimal
for example 40% would be 0.4
then times that by the number you are finding the percentage of :)

Percentages are compared to 100% because ALL of something (say a dollar) is 100% of it.
To figure what percent of something is (say 56% of 80) you just think of the words "percent of" as "Multiply."  So 56 X 80 = 4,480 BUT NOW you MUST put your decimal point two places (for the two zeros in 100) to the LEFT.  So 4480. Becomes 44.80 so 56%of 80 is 44.8

If you don't understand why the zero was dropped, it is because zeros past the numbers to the right of a decimal point are treated the same as zeros to the left of the numbers on the left of the decimal point.  EX:  007. Is just 7, you don't need the zeros in front of it to tell you this is 7 because its place in the ones column tells you it's 7, but if the number was .007 you would need them, because the zeros there let you know that this 7 is in the one thousandth place and the number is actually the fraction 7/1000; but if the number is .700 we know the fraction is 7/10 whether or not we have zeros to the right of it, so the zeros to the right of it are unnecessary and just writing .7 is fine.

By a certain percant ,we mean that many hundredths.Thus,x percent means x hundredths , written as x%
eg:-    
        20%=20/100
To express a/b as a percent : we have a/b=(a/b*100)%
eg:-
       1/4=(1/4*100)%=25%;
If price increase by r%, then the reduction in consumption
[r/(100+r)*100]%
If the price decrease by r%, then the increase[r/(100-r)*100]%

The easiest way to calculate % is

let us assume x,y

then  x = current amt, & y = Total amt.

by using the formula

percentage = (x/y)  * 100

           we can find the percentage.

e.g.

current amt is 20, total amt is 100,
                                              then we can find  the rate..
by using the fromula!!!!

x=20 & y=100
percent= (20/100)*100

20%        
             HaHaHa   thats it..

Percentage is nothing but the efficiency calculation in a given event

simple formula for percentage is
percentage=(number of times given work has done divided by total number of times the work has done) multiplied with cent.

Percentage=(number of times work done/total number of times work done)*100

simply remember as
percentage=(part of value/total value)*100

          percentage refers if there is 100 parts, the efficiency  of work is in how many part.

(given amount / total amount )*100 like
6o/75*1oo
thank you

the best and easy way to calculate %age is to divide that no with the tiotal no and finally multiply with hundred.......

like.....10 is what % of 100?

10/100=1/10
1/10*100=10%.

percentage is defined as the product of (ratio of  the obtained outcomes to the total actual outcomes ) to hundred.
i.e                   obtained outcomes
       % =          -------------------------         *    100  .
                        total actual outcomes

Percent means for every hundred. A fraction whose denominnator is 100, is called a percentage and the numerator of the fraction is known as the rate of percent.
It is generally expressed by %.
Example- Evaluate 10% of 250
Solution- 10% of 250 = 10/100 of 25
                                       = 10*250/100
                                       = 25

First we take the value 70 & we have to calculate its 5%.So we multi it by 5& after that we divide it by 100 .Hence the value final will be 70*5/100=0.35

given value or the amount of value given from the total values is divided by the total values is multiplied by 100 is the persentage of given values
eg:- totally there are 10 oranges.of those 10 i will give you 5.percentage of orrange that is with u is (5/10)*100
ie:- 50% is with you..

if total mark of one is 892 out of 1000.then % is
892/1000*100=89.2%

amount into percentage
e.g    amount 100
rate of percentage 10%

100*10%=10

How does one answer this?

Something ends at 500, marking a 66% rise from a starting number. What was the starting number?

I am waiting for for 56 documents. 13 have been received. What is the percentage that I have received?

I'm just a Math Moron!

13 of 19

Lets say you got 15 out of 20.
You multiply 15 by 100.
15x100=1500.
Then, you divide that by 20.
1500/20=75%

the mathematical equation is:
15x 100 / 20 = 75%!
SImple, eh?

X=y+100

You can calculate percentage  by dividing by 100

Marks obtained divided by total marks multiply by 100

Take the fraction and multiply by 100.

That is not too hard. Lets say you want to know what 5% of 20 is. The 20 would be your 100%. So you divide 20 thru 100 and that gives you 1% ( 0.2 ) then you multiply by 5 that gives you the 5%.( 1 ) . So your 5% from 20 is 1 . I hope that this helps you a little bit .

Just add your marks and divide it with total marks.
E.g. If u score 99out of 100 in maths 95out of 100  in english then your percentage will be
99+95=194 and 100+100=200
therefore 194 out of 200 194/200=0.97
add two decimals
i.e 97%
thanks!!!!!!!!!!!!!!!!!!!!!!

When u have a decimal, move the decimal point 2 places to the right and you should get the percentage

Percentage is nothing but whatever we have out of something, we should calculate that out of 100.
Formula:   
                   first let us take x which is out of y
                   now we want to find the percentage of the above
                   i.e  we should find x out of 100.  
                   percentage=(x/y)*100

    thus we should calcualte the percentage.

Percentage is nothing but whatever we have out of something, we should calculate that out of 100.

Suppose, you have scored total 450 marks in examination in five subject, each subject have tatal 100 marks.
then your percentage in the exam. is calculated as follow

Total marks of five subject = 500
Total marks obtained in
                the five subject     = 450
By alligation,
if a=450 marks out of t = 500 then
how many marks c=? out of 100

percentage  =  Total marks obtained / Total marks *100

A percentage is a part of hundred if in one test u score 85 marks out of hundred itd mean that u got 85% marks e.g  TOTAL MARKS =100
MARKS OBT=85
MARKS OBT*100/TOTAL MARKS

To calculate percentage here are 2 examples.
1- how much is 10% of 500?
the calculation will be 500 divided by 100 multiply by 10 will give you the 10 % of 500.
500 / 100=5 x 10 = 50.

2- if you bought something for $400 and sold it for $500.
what's the % of profit you earned?
500 divided by 400 the answer any thing above the decimal point is the percentage of profit.
500 / 400 = 1.25 . so 25 is the % of profit.
