Answer 2

Calculating the Number of Children Remaining in the Camp

To calculate the number of children remaining in the camp, we can use the following steps:

1. Calculate the number of children who went on the hike: \( \frac{2}{7} \) of the total number of children. 2. Calculate the number of children who went on the excursion: \( \frac{2}{9} \) of the total number of children. 3. Subtract the total number of children who went on the hike and the excursion from the total number of children to find the number of children remaining in the camp.

Step 1: Calculate the Number of Children Who Went on the Hike

The number of children who went on the hike is \( \frac{2}{7} \) of the total number of children.

Step 2: Calculate the Number of Children Who Went on the Excursion

The number of children who went on the excursion is \( \frac{2}{9} \) of the total number of children.

Step 3: Calculate the Number of Children Remaining in the Camp

To find the number of children remaining in the camp, we subtract the total number of children who went on the hike and the excursion from the total number of children.

Let's calculate the number of children remaining in the camp using the given information.

Calculation

Total number of children in the camp = 630

Number of children who went on the hike = \( \frac{2}{7} \times 630 \)

Number of children who went on the excursion = \( \frac{2}{9} \times 630 \)

Number of children remaining in the camp = Total number of children - (Number of children who went on the hike + Number of children who went on the excursion)

Result

The number of children remaining in the camp can be calculated using the above steps and the given information.
