Question

Luis folded 8 shirts in 10 minutes and 18 shirts in 20 minutes.
Carly folded 3 shirts in 5 minutes and 9 shirts in 15 minutes.
Determine if the number of shirts Luis folds per minute represents a
proportional relationship. Explain your answer.
What is Carly’s unit rate written as a decimal? shirts per minute
Can you compare Luis and Carly’s unit rates for folding clothes?

Answer 1

To answer the first question let's make up ordinary fractions: 8/10 and 18/20. They must be equal. If we reduce each of them, we get 4/9 and 9/10, so we get non-proportional relations.

Answer to the second question: First, you need to prove the proportionality of the relationship. We do the same as in the first question. We get that the relationship is proportional and will be equal to 3/5. Hence the answer is 0,6.

The answer to the third question: Since Louis has a non-proportional relationship, and Carly has a proportional relationship, then we can't compare Luis and Carly’s unit rates for folding clothes.
