Question 1118225
<br>
The information about the number of men and women is irrelevant to the question that is asked.<br>
The number of adults is one-third the number of children; it's probably easier for most people to work the problem if we rephrase that to say there are three times as many children as adults.<br>
Then with a total of 3600 people we can mentally find the answer that there were 2700 children and 900 adults.<br>
Or, if you need an algebraic solution....
let x = number of adults
then 3x = number of children
x+3x = 3600
4x = 3600
x = 3600/4 = 900<br>
The number of children is 3x = 3*900 = 2700.
