Answer:

D: 5 : 8 and 20 : 32

Step-by-step explanation:

A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.

B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.

C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.

D is correct because 5 x 4 = 20 and 8 x 4 = 32.

another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....

Easy right!?
