Question

divide 75 in two parts such that the ratio of the parts be 7:8

Answer 1

Let the number be 7x and 8x
Then,
7x + 8x = 75
15x = 75
X = 75/15
X = 5
So,the divided parts are :-
7 * 5 = 35 and
8 * 5 = 40
Hope it helps...!!!

Answer 2

let ratios be 7x ,8x
7x+8x=75
15x=75
x=75/15
x=5

then
7x=7×5=35
8x=8×5=40

to check

add

35+40=75
75=75
