Question

the numerator of a friction is 6 less than the denominator . if 1is added to both the numerator and the denominator , the friction become 1/2 . find the friction​

Answer 1

let the denominator be x.

so , the numerator is x-6

so, [(x-6)+1]/[x+1] = 1/2

or, x-5/x+1 = 1/2

or, 2(x-5) = x+1

or, 2x-10 = x+1

so , x = 11

so the fraction is 5/11
