Answer:
c. 6/15 = 10/25
Step-by-step explanation:
Using the hint, we can form the cross products of the offered choices:
a. 6(12) vs 9(9) ⇒ 72 vs 81 . . . not a proportion
b. 8(21) vs 16(10) ⇒ 168 vs 160 . . . not a proportion
c. 6(25) vs 15(10) ⇒ 150 vs 150 . . . IS A PROPORTION
d. 4(27) vs 14(6) ⇒ 108 vs 84 . . . not a proportion
__
The cross products are the same for choice C, so that is a pair of ratios that form a proportion:
6/15 = 10/25
