Answer:
there are 20 girls in the class
Explanation:
the ratio of 3 boys to 5 girls
you are given the total number of students (boys and girls) = 32
write equation
x (3 + 5) = 32
8x = 32
x = 4
now distribute the x into girls which is 5x or 5(4) = 20 girls
additionally 3x is for boys or 3(4) = 12 boys; which adds up to 32
