Find Original Fraction...2

[nycmathguy]

Let 20% = 0.20.

Let 25% = 0.25.

Numerator of original fraction = (x + 0.20).
Denominator of original fraction = (x - 0.25).

My set up:

(x + 0.20)/(x - 0.25) = 4/5

Yes?

(x + 0.20)/(x - 0.25) = 4/5-> it's not correct
you are given
x+20% of x=> (x+0.20x)=(x+x/5)->numerator
y-25% of y=>(y-0.25y)=(y-y/4)->denominator

Thanks for the correction.
