Which of the following are equivalent ratios?

15 to 20
6 to 8
8 to 12
9 to 12

So yuo simplyfly

15:20=3:4

6:8=3:4

8:12=2:3

9:12=3:4

so your answer is not c

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.
