1/3 + 1/3 = 1+1/3(common)
= 2/3

1 3/4 Cup Divided By Two
Mathematically :
1(1 denotes as one) 3/4=3/4
3/4 divided by 2
3/4/2=3/8
if the Query is like divided by two(cups)
3/4/2(3/4)= 1/2
Its half cup

7+2+5 = 143547
7*2=14
7*5=35
14(ans 1)+35(ans 2)=49(ans 3)
49(ans 3)-2(middle digit)=47
Finally
7+2+5 = 143547
