It is. You can tell a couple of ways.
If you multiply the denominator of the 1st X the numerator of the 2nd and get the same answer when you multiply the denominator of the 2nd X the numerator of the 1st, then the fractions are proportional.
If you look at the pair you've shown, you can see that if you multiply the numerator and the denominator of 5/8 X 15, you get 75/120.

locate the least basic denominator, that's one hundred twenty, divide it by 8 to work out which you get 15. multiply the 15 circumstances 5 interior the numerator and get seventy 5. as a results of fact the numerators are aspects as properly as a results of fact the denominators, they're proportional 5*15=seventy 5 -- --- 8*15=one hundred twenty
