This is a very interesting question.
The first statement says
1/3 girls = 1/6 of the total Multiply both sides by 3
3(1/3) girls = 3(1/6) total
girls = 1/2 of the total
The boys must be 1/2 as well because all the students who are not girls must be boys.
Ratio (boys / girls) = 1/2 // 1/2 = 1
The ratio is 1
