Question

The numerator of a fraction is 4 less then its denominator if one is is added Tu both what is numerator and denominator the fraction becomes 12 find the fraction ​

Answer 1

EXPLANATION

Let the numerator be x. Then,

The numerator of a fraction is 4 less than

its denominator. So,

Numerator of the fraction = x

Denominator of the fraction = x + 4

If one is added to both, the fraction

becomes 12.

Now, numerator = x + 1

Denominator = x + 4 + 1 = x / 5

= x + 1 ÷ x + 5 = 12

= x + 1 = 12 ( x + 5 )

= x + 1 = 12x + 60

= x - 12x = 60 - 1

= - 11x = 59

= - x = 59 / 11

= x = - 59 / 11

So, numerator of the fraction is - 59 / 11

Denominator = - 59 / 11 + 4

= - 15 / 11
