Question

By what percent will a fraction change if its numerator is decreased by 60% and its denominator is decreased by 20%? THANK YOU SO MUCH TO WHOEVER ANSWERS IT I HAVE VERY LITTLE TIME!

Answer 1

decreased by 50%

Explanation:

`(x)/(y)`

100% - 60% = 40% = 0.4

100% - 20% = 80% = 0.8

`(0.4x)/(0.8y)` =
`(x)/(2y)` = 0.5 ×
`(x)/(y)` ⇒ the original fraction is decreased by 50%
