There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?
If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = <<133-33=100>>100 people.
That means that there were 100 / 2 = <<100/2=50>>50 girls at the camp.
