Answer: A= 36
Step-by-step explanation:
6+6=12
12+12=24
add 12 and 24=36
The ratio is 4:5
so girls=4x
and boys=5x
(because you don't know how many boys or girls there are)
then the equation would be
4x+5x=18
9x=18
so x=2
then 2 times 4 which equals 8
and 2 times 5 which equals 10
so there are 8 girls and 10 boys
