Question
There are 72 people in a park. If 18 of them are adults and the rest are children, what percent of people are children?
Solution
Step 1: Find out the total number of children in the park. We know that there are 72 people in total and 18 of them are adults. So, the number of children is 72 (total people) - 18 (adults) = 54 children.
Step 2: Now, we need to find out what percent of the total number of people are children. The formula to find the percentage is (Number of children / Total number of people) * 100.
Step 3: Substitute the values into the formula: (54 children / 72 total people) * 100 = 75%.
So, 75% of the people in the park are children.
