There are between 24 and 40 students in the class

the ratio for boys to girls is 4:7

how many students are in the class

33

Step-by-step explanation:

Let's take the constant of proportionality to be X

4x+7x=between 24 to 40

11x = 24 to 40

X should be a natural number therefore the number of students should be multiple of 11

Only multiple of 11 between 24 and 40 is 33

33 Students

Step-by-step explanation:

4+7=11 so the number of students in the class must be a multiple of 11. The only multiple of 11 between 24 and 40 is 33.
