1.B%2BG=250

%282%2F5%29G wore glasses so %283%2F5%29G did not wear glasses.
%281%2F10%29B wore glasses so %289%2F10%29B did not wear glasses.

%283%2F5%29G=%289%2F10%29B
6G=9B
From eq. 1,
6B%2B6G=6%28250%29
Substituting,
6B%2B9B=1500
15B=1500
B=100
So then,
6G=900
G=150
100 boys, 150 girls total.
%282%2F5%29%28150%29=60 girls wore glasses.
%281%2F10%29%28100%29=10 boys wore glasses.
