Which of the following pairs of numbers contain like fractions?

A. 3

/2

and 2

/3

B. 6

/7

and 15

/7

C. 5

/6

and 10/12

D. 31

and 43

/4

C. 5/6 and 10/12

If you simplify 10/12 but the greatest common factor of 10 and 12, which is 2, you get the answer of 5/6. Now if you multiple 5/6 by two, you get 10/12. Either way, both fractions are clearly equivalent.
