Step-by-step explanation:
let fraction be =1/x
numerator increased by 2=1+2
Denominator by 1=x+1

if both decreased by 4
=1-4/x-4=4/5
we get answer if we slove both equations

Step-by-step explanation:
Let the fraction be x/y
therefore x+2/y+1 =13/15
15x + 30 = 13y +13
15x-13y + 17 = 0........(1)
also x-4/y-4 =4/5
5x- 20 = 4y - 16
5x- 4y = 4
on solving the equations we get y=29 and x = 24
therefore fraction is 24/29
