If school A has a boys and b girls, and school B has c boys and d girls, then
a/c = 2/1
b/d = 4/5
a+b = c+d
we want to find a/b
a = 2c
5b = 4d
a-c = d-b
a-(a/2) = (5b/4)-b
a/2 = b/4
a/b = 2/4 = 1/2
a/c = 2/1
b/d = 4/5
a+b = c+d
we want to find a/b
a = 2c
5b = 4d
a-c = d-b
a-(a/2) = (5b/4)-b
a/2 = b/4
a/b = 2/4 = 1/2
