Answer 2

Calculation of Remaining Children in the Swimming Competition

To calculate the number of children remaining in the swimming competition, we need to subtract the number of children who were eliminated in the qualifying round from the total number of children who initially participated.

Given the following information: - Total number of boys: 15 - Total number of girls: 12 - Number of children eliminated in the qualifying round: 13

We can calculate the total number of children who initially participated by adding the number of boys and girls together: - Total number of children who initially participated = Number of boys + Number of girls

Let's calculate the total number of children who initially participated: - Total number of children who initially participated = 15 (boys) + 12 (girls)

Now, let's calculate the number of children remaining in the competition: - Number of children remaining = Total number of children who initially participated - Number of children eliminated in the qualifying round

Substituting the values we have: - Number of children remaining = (15 + 12) - 13

Calculating the expression: - Number of children remaining = 27 - 13

Therefore, the number of children remaining to participate in the swimming competition is 14.
