Question

What number must be subtracted from
each term of the ratio 5 : 7 so that the ratio
becomes 2 : 3 ?​

Answer 1

Answer:

Let the number to be subtracted be y

5 - y/7 - y = 2/3

2(7 - y) = 3(5 - y)

14 - 2y = 15 - 3y

3y - 2y = 15 - 14

y = 1

Answer 2

5-x/7-x=2/3

3(5-x)=2(7-x)

15-3x=14-15

-x=-1

X=1
