Out of the 21 students in mrs Clark’s class by 3/7 of the class are boys

There are 9 boys and 12 girls in mrs Clark's class

Step-by-step explanation:

We are given that mrs Clark has 21 students, of which 3/7 are boys

In order to find the number of boys, we multiply 21 by 3/7 which results in 9

This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12

therefore there are 9 boys and 12 girls in mrs Clark's class
