I don't understand how to get the answer to this one. I know the answer is 13, but it had a poor explanation. Please help.

On a soccer team consisting of 21 children, some of which are boys and some of which are girls, exactly of the boys and exactly of the girls attended the end of the season pizza party. What is the greatest number of children on the team who could have attended the party?

I copied and pasted the question. It has you guess the number of boys total, then guess how many girls would be considered 1/3. It's really confusing. I'm hoping for a better answer on here. The answer is 13.

the solution is more reasoning than calculation
since 2/3 boys attend the party and 1/3 girls attend the party
you would want to maximize the number of boys

girls should be at least 3 so that 1/3 *3 is a number.
so total 18 boys and 3 girls
2.3*18=12
1/3 *3=1
max 12+1=13 children can attend the party

girls number cannot be 0. because it is given the exactly 1/3 of girls attend the party.
The powers of two are bloody impolite!!
