Choose the statement that correctly lists equivalent ratios.

A.

1 : 6 = 20 : 120 = 5 : 30

B.

1 : 6 = 4 : 18 = 6 : 36

C.

1 : 8 = 20 : 120 = 3 : 24

D.

1 : 8 = 3 : 32 = 5 : 48

A. 1 : 6 = 20 : 120 = 5 : 30

1*20 : 6*20 = 20 : 120

1*5 : 6 * 5 = 5 : 30

So they are equivalent ratios

B. 1 : 6 = 4 : 18 = 6 : 36

1*4 : 6*4 = 4 : 24 which is not equivalent to 4 : 18

so, they are not equivalent ratios

C. 1 : 8 = 20 : 120 = 3 : 24

1*20 : 8*20 = 20 : 160 which is not equivalent to 20 : 120

so, they are not equivalent ratios

D. 1 : 8 = 3 : 32 = 5 : 48

1*3 : 8*3 = 3 : 24 which is not equivalent to 3 : 32

so, they are not equivalent ratios

a. yes b. no c. no d. no
