The answer is C because when I simplified both the fractions,the denominators became 5.9/15 will become 3/5.So,the other fraction must be 3/5 because they are equivalent.When you change the denominators to 10 and 15,you change the numerators to 6 and 9.The fractions are 6/10 and 9/15.C is 6.So,the answer is 6

The answer should be C because if you convert both denominators to 30 then for 9/15 you get 18/30 and for 6/10 you get 18/30 so in conclusion the answer should be C.

The common denominator is 30. 9/15 expanded is 18/30. As A is over 10, we have to simplify 18/30 by 3, making 6/10. This means A=6.

The denominators seem to be following the 5 times table so if this was a pattern, the fraction before would be 35 and the numerators would follow the 3 times so the middle fraction should be 6/10.

The denominators seem to be following the 5 times table so if this was a pattern, the fraction before would be ⅗ and the numerators seem to be following the 3 times table. Ergo, the middle fraction should be 6/10.
