Problema Solution
The ratio of boys and girls is 2:3 so if there are 80 students,how many girls will there be?
Answer provided by our tutors
let
b = the number of boys
g = the number of girls
the ratio of boys and girls is 2:3
b : g = 2 : 3 cross-multiply
3b = 2g
there are 80 students
b + g = 80
by solving the system of equations
b + g = 80
3b = 2g
we find
b = 32 boys
g = 48 girls
