Answer:
No, they don't.
Step-by-step 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!
