Answer:

38 : 133 and 16 : 56 are equivalent

Explanation:

Given

1)
38 : 133 and
16 : 56

2)
15 : 20 and
28 : 56

Required

Determine which is equivalent

1)
38 : 133 and
16 : 56


Ratio = 38 : 133

Divide by 19


Ratio = 2:7 --- can't be further simplified


Ratio = 16 : 56

Divide by 8


Ratio = 2:7

Hence:


38 : 133 and
16 : 56 are equivalent

2)
15 : 20 and
28 : 56


Ratio = 15 : 20

Divide by 5


Ratio = 3 : 4


Ratio = 28 : 56

Divide by 28


Ratio = 1:2

Hence, both are not equivalent.
