+770 So, let b = # of boys and g = # of girls.
1/3 of b = 2/5 g, every boy has a girl to pair up with and vice versa in the group.
b/3 = 2g/5
b + g = 88
We can write a variable in terms of the other, like this: b = 88 - g
(88 - g) / 3 = 2g / 5
440 - 5g = 6g
440 = 11g
Hmm, nice!
g = 440 / 11 = 40
So, there are 40 girls.
Then, there are 88 - 40 = 48 bois!
