Answer 3

Calculation of Total Weight of Paper Collected by Children

To calculate the total weight of paper collected by the children, we need to determine the weight of paper collected by the boys and the weight of paper collected by the girls.

Given that the boys collected 72 kg of paper, which is 4 times more than what the girls collected, we can set up the following equation:

72 kg = 4 * weight of paper collected by the girls

To find the weight of paper collected by the girls, we can divide 72 kg by 4:

Weight of paper collected by the girls = 72 kg / 4 = 18 kg

Now, to find the total weight of paper collected by the children, we can add the weight of paper collected by the boys and the weight of paper collected by the girls:

Total weight of paper collected by the children = 72 kg + 18 kg = 90 kg

Therefore, the children collected a total of 90 kg of paper.
