Question 1118225: At the fair there were half as many men as women. The number of adults was a third that of children. There were 3,600 people at the fair. How many children were there? Found 2 solutions by Fombitz, greenestamps:Answer by Fombitz(32388) (Show Source):
The information about the number of men and women is irrelevant to the question that is asked.
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.
Then with a total of 3600 people we can mentally find the answer that there were 2700 children and 900 adults.
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
