Question

there are 27 trophies in the school display case 12 are for swimming what fraction of the trophies in lowest terms are not for swimming?

Answer 1

5/9

Explanation:

given that 12 out of 27 trophies are for swimming that means 15 are not (27-12)

with this logic the relationship between non swimming trophies and total trophies is 15/27

dividing the top and bottom by 3 gives you 5/9
