Answer:
100
Step-by-step explanation:
First we get the ratio of 8:3 for the amount of boys to girls.
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 8 + 3 = 11
Part A = 8 and Part B = 3 are numerators for each fraction.
The fractions are then:
8/11 and 3/11
8/11 for boys
and 3/11 for the girls
Now we just multiply 220 by these fractions:
220 * 8/11 = 160
220 * 3/11 = 60
Then subtract:
160 - 60 = 100
Answer:
There are 60 girls and 160 boys
