Question

Numerator of a rational number is less than its denominator by 8 . If the numerator is increased by 17 and the denominator decreased by 1 number is 3/4 . Find rational number

Answer 1

let n be x and d be y
x=y-8 or y=x+8
x+17/y-1=3/4
cross*ly
4 (x+17)=3 (y-1)
4x+68=3y-3
4x+68=3(y+8)-3
4x+68=3x+24-3
●1x=-47
●y=x+8
y=-47+8
●y=-39
then the no. is -47/-39
