Answer:

No, they don't.

Explanation:

I'm going to divide 18 by 9 and 30 by 20. If the quotients are the same, then we do have a proportion.

18 ÷ 9 = 2

30 ÷ 20 = 1.5

The quotients aren't the same. Same thing if you convert the fractions to decimals:

9 ÷ 20 = 0.45

18 ÷ 30 = 0.6

This means the two values do NOT form a proportion.

Hope this helps! Have a great day!
