The number is fairly easy to come across. The first thing that I see is that there are 45 students at the camp. This means, based on the clues given to me, that the number of 6th graders is odd. Because the number of 6th graders is half the number of 7th graders, and 8th grade equals 7th grade, that you have to use an even number less than 20, but more than ten.This leaves the numbers 14 and 18. Now we use trial and error. Half of 14 is 7. 14+14=28
28+7=35
35≠45
Half of 18 is 9.
18+18=36
36+9=45
45=45
So the answer is as follows:
6th grade: 9
7th grade: 18
8th grade: 18
