The sum of the numerator and denominator of a fraction is 156, which is about 4 out of 9. What is the original fraction Is it 48 out of 108? I copied it. I want to know how to get it

Let the numerator X and denominator 156-x / 156-x = 4 / 9 and x = 48, then the fraction is 48 / 108

The sum of the numerator and denominator of a fraction is 76, which is about one third of the total?

19/57

For the simplest fraction, the sum of numerator and denominator is 40. If the numerator and denominator are reduced by three, it will get seven tenths

If the denominator is x, the original fraction is x / 40-x, so x-3 / 40-x-3 = 7 / 10, so 17x = 289, so x = 17, so the original fraction is 17 / 23
