This​ week,957 people went to the beach. Last​ week, 1197 people went to the beach. The number of people who went to the beach fell by what​ percent?

To find the percentage decrease in the number of people who went to the beach, we need to calculate the difference between last week's number and this week's number and then express it as a percentage of last week's number.

Number of people decrease = 1197 - 957 = 240 people
Percentage decrease = (Number of people decrease / Last week's number) * 100
= (240 / 1197) * 100
≈ 20.04%

Therefore, the number of people who went to the beach fell by approximately 20.04%.
