Question

if the denominator of a fraction is in reased by 4 then the fraction becomes 5/8.if the numerator is 11 less than the denominator find the numerator​

Answer 1

hey mate here is ur answer

let the fraction be x/y.

by given condition

x/(y+4)=5/8

8x=5y+20

8x-5y=20-----(1)

x=y-11.

x-y=-11

solving the equation

8(y-11)-5y=20

8y-88-5y=20

3y=108

y=36

x=25

hence fraction is 25/36.

hope it helps.
