10 : ? = Number of Boys to girls

10 : 12 = Number of Boys to girls

12

Step-by-step explanation:

The 5 parts of the ratio represents 10 boys.

Divide number of boys by 5 to find the value of one part of the ratio.

There are 6 parts of the ratio representing girls, thus

6 × 2 = 12 ← number of girls in the class
