How To Calculate Percentage?
40 Answers - Sort by: Date | Rating
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%.

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 :)

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.

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%

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%
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 :-((
like it
thinking out of the box
Its so simple...
Tnx!
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%
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 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 =
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.
for example 40% would be 0.4
then times that by the number you are finding the percentage of :)

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.

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]%
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.
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..
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.
like.....10 is what % of 100?
10/100=1/10
1/10*100=10%.
i.e obtained outcomes
% = ------------------------- * 100 .
total actual outcomes
It is generally expressed by %.
Example- Evaluate 10% of 250
Solution- 10% of 250 = 10/100 of 25
= 10*250/100
= 25
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..
Something ends at 500, marking a 66% rise from a starting number. What was the starting number?

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?

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!!!!!!!!!!!!!!!!!!!!!!
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
MARKS OBT=85
MARKS OBT*100/TOTAL MARKS

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.
