Answer 3

Calculation of the Number of Preschoolers in the Zoo

To calculate the number of preschoolers who visited the zoo on that day, we need to use the information provided in the question. Let's break down the information step by step:

- The total number of people who visited the zoo in one day was 456. - Out of these 456 visitors, 216 were adults. - The number of schoolchildren was twice as less as the number of adults. - The remaining visitors were preschoolers.

To find the number of schoolchildren, we can divide the number of adults by 2:

Number of schoolchildren = Number of adults / 2

Let's calculate it:

Number of schoolchildren = 216 / 2 = 108

Now, to find the number of preschoolers, we subtract the sum of adults and schoolchildren from the total number of visitors:

Number of preschoolers = Total number of visitors - (Number of adults + Number of schoolchildren)

Number of preschoolers = 456 - (216 + 108) = 456 - 324 = 132

Therefore, there were 132 preschoolers who visited the zoo on that day.
