Question

The numerator of a fraction is 3 times the denominator. If 5 is subtracted from the numerator, and added to the denominator, the resulting fraction is equal to 16/12. Find the original fractio

Answer 1

numerator 3x
denominator x

Original fraction: 3x/x

It's obvious to see the answer is 3, but if you want to take the long route:

16/12 = (3x-5)/(x+5)

So the fraction would be 21/7 which equals 3

Answer 2

3/1
