Question

the sum of numerator and denominator of a fraction is 12 if the denominator is increased by 3 then the fraction becomes 1 by 2 find the fraction
​

Answer 1

Answer:

5/7

Sum is 12 so Let the numerator be x and denominator is 12 - x .

Thus fraction formed = x/12 - x

Now according to the question,

x/ 12 - x + 3 = 1/2

x / 15 - x = 1/2

by cross multiplication,

15 - x = 2x

15 = 3x

5 = x

So the numerator of fraction is 5 and denominator is 12 - x = 12 - 5 = 7

So the fraction formed is 5/7.
