Salama likes cooking pancakes for her family. On Sunday, she made 15 pancakes in 2 hours. On Monday, she made 21 pancakes in 3 hours, and on Tuesday, she made 15 pancakes in 2 hours. 4 The relationship between the number of pancakes and the time taken to make them can be expressed as a nonproportional relationship. or proportional relationship.?

Answer 1

Answer: The relationship between the number of pancakes and the time taken to make them is a proportional relationship.

Explanation:

To determine whether the relationship between the number of pancakes and the time taken to make them is proportional or nonproportional, we need to compare the ratios of pancakes to time for each day.

Let's calculate the ratios:

On Sunday: 15 pancakes ÷ 2 hours = 7.5 pancakes/hour

On Monday: 21 pancakes ÷ 3 hours = 7 pancakes/hour

On Tuesday: 15 pancakes ÷ 2 hours = 7.5 pancakes/hour

Comparing the ratios, we can see that the number of pancakes per hour is consistent for all three days. The ratio remains the same at 7.5 pancakes per hour for Sunday and Tuesday, and 7 pancakes per hour for Monday.

Since the ratios are the same, we can conclude that the relationship between the number of pancakes and the time taken to make them is proportional.

Therefore, the relationship between the number of pancakes and the time taken to make them is a proportional relationship.

I hope this helps :)
