a. neither is a proportion
b. 8 over 4 = 12 over 6 only
c. 16 over 8 = 24 over 12, 8 over 4 = 12 over 6
d. 16 over 8 = 24 over 12 only

Answer 1

The correct answer is b. 8 over 4 = 12 over 6 only.

In the first comparison, 16 over 8 = 24 over 12 simplifies to 2 = 2, so it is a proportion.
In the second comparison, 8 over 4 = 12 over 6 simplifies to 2 = 2, so it is also a proportion.
