Well, 1/3 is equal to 0.3, and 1/4 is equal to .25, so it can't be a. 3/4 is equal to .75 and 6/9 is equal to 0.6, so it can't be b. 5/8 is equal to 0.625 and 20/32 is also equal to 0.625, so it could be c. 7/9 is equal to 0.7 and 21/28 is equal to 0.75, so it can't be D. Your best bet is C. Because both sides of C are equal. C 5/8=20/32
