The ratio of boys to girls in a math class is 2 to 3. If the class has 20 students, how many of them are girls?

12 girls

Step-by-step explanation:

(Left is boys, middle is girls, right is total students)

2 3 = 5

4 6 = 10

6 9 = 15

8 12 = 20

Another way to solve:

(Left is boys, middle is girls, right is total students)

2 3 = 5

x 4 x4 x4

8 12 = 20

(We know to multiply by 4 because the total students is 20, so 5 times 4 is 20, so we would multiply by 4 to get the answer)

12 girls and 8 boys make 20 students.

8:12
