Answer:
Explanation:
If 60% of the people were adults, then 40% of the people were children (since the total percentage must add up to 100%).
To find out how many children were there, we need to know the total number of people. We can use the number of adults to find this:
Let X be the total number of people. Then, we know:
60% of X = 72 (the number of adults)
40% of X = the number of children
To solve for X, we can divide both sides of the first equation by 60% (or 0.6):
X = 72 / 0.6 = 120
So there were 120 people in total. To find the number of children, we can use the second equation:
Number of children = 40% of 120 = 48
Therefore, there were 48 children at the school play.
