No, not all of those fractions are equivalent. 5/20 reduces to 1/4. 8/40, 3/15, and 6/30 reduce to 1/5, so they are equivalent.
8 / 36 = 2 / 9 .
47
8/9
7/8 is in its simplest form.
We can take 16/30 and reduce it to 8/15 by dividing the numerator and denominator by 2. We cannot reduce that fraction any more.
There is no way to reduce 7 over 8 because it is already in simplest form.
30/5 = 6
Divide numerator and denominator by 2. 30/8 = 15/2
