Answer:
The answer is: both class have the same ratio.
Step-by-step explanation:
Get the ratio of tall to short. Divide Tall by Short:
Jack's class:
18/10 = 1.8 tall one for every short one
Michael's class:
54/30 = 1.8
The ratio is the same!
You can further prove this by multiplying 18 times 3 and getting 54, and 10 times 3 and getting 30.
