Question

The supermarket has 40 aisles. 20% are empty, without any shoppers. How many empty aisles are there in the supermarket?

Answer 1

To find the number of empty aisles, you calculate 20% of 40, which equals 8. Thus, there are 8 empty aisles in the supermarket.

Step-by-step explanation:

To find out how many empty aisles there are in a supermarket that has 40 aisles with 20% being empty, we need to calculate 20% of 40. Here's the step-by-step explanation:

1. Understanding that 'percent' means 'per hundred', we translate 20% into a decimal by dividing 20 by 100, which gives us 0.2.
2. We then multiply the total number of aisles, which is 40, by the decimal 0.2 to find the number of empty aisles.
3. So, 40 aisles multiplied by 0.2 equals 8.

Therefore, there are 8 empty aisles in the supermarket.
