Task Analysis

To solve this problem, we need to determine the number of adults in the theater given that there are 12 rows of children with 10 children in each row, and the number of adults is three times less than the number of children.

Solution

Let's break down the problem step by step:

1. Calculate the total number of children in the theater: - There are 12 rows of children. - Each row has 10 children. - Therefore, the total number of children is 12 rows * 10 children per row = 120 children.

2. Calculate the number of adults in the theater: - The number of adults is three times less than the number of children. - Therefore, the number of adults is 1/3 of the number of children. - Calculate 1/3 of 120 children: 120 children / 3 = 40 adults.

Answer

There are 40 adults in the theater.
