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 :)
