The numerator and denominator of a real fraction are two adjacent odd numbers. If you add 3 to the denominator, the score will be about three quarters. What was the original score?
It turns out that the difference between numerator and denominator is 2.

Later, the difference between numerator and denominator was 2+3=5.

therefore

3/4 = 4× 5/3× 5 = 15/20.

that is

Molecule = 15, denominator = 17.

Original score = 17 15.
