Question

the denominator of a fraction is 4 more than its numerator(y).The value of the fraction was 3/4 or more. find the least value of y.

Answer 1

The denominator of a fraction is 4 more than its numerator

so

let numberator be x 

then denomintor is x +4

now,

on subtracting 1 from each the number and the denominator.the fraction become 1/2

lets form an equation

x  - 1/ (x + 4)  -1 = 1/2

x  - 1/ x + 3 = 1/2

lets cross multiply

2(x - 1) = 1(x + 3)

2x - 2 = x +3

2x - x = 2 +3

x = 5

now denominator is x +4

= 5+4 = 9

so fraction is 5/9
