You need to find the one that have common denominators

anonymous · Answer

15 and 55 dont have no common denominator
24 and 35 have no common denominator
18 and 90 are common denominator
11 and 25 have no common denominator
18 and 90 are the only ones with a common denominater

anonymous · Answer

so is the 18 was 9 it would be multiplied by 10 it would be 90 but it is 18 so it is 5
So 5$$\frac{ 5 }{ 25 }$$
