60 percent. I don't know why but I am 100 percent sure of my answer. I calculated it

Vaughn Mcgee · Answer 2

We have three hundred students in total.

For every 3 boys, there are 2 girls. This can also be said as 1.5g = b

We can find the answer by setting up two equations.

g + b = 300

b = 1.5g

Then, when can use substitution method to put 1.5g in for b and we have g + 1.5g = 300

Solve for g to find girls and plug back in for boys
