Question

By what percent will the fraction change if its numerator is increased by 25% and its denominator is increased by 20%? please answer it by 4:20

Answer 1

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %

Explanation:

Let the fraction be represented as
`(x)/(y)` where x is the numerator and y is the denominator

Given that numerator will increase by 25 %, = 25% x

= 0.25 x

Given that denominator will increase by 20 %, = 20% y

= 0.2 y

The new fraction becomes =
`(x + 0.25 x)/(y + 0.2 y)`

=
`(1.25 x)/(1.2 y)`

=
`((1.25)/(1.2) ) (x)/(y)`

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %
