Answer:

33

Step-by-step explanation:

To find the number of students, we must find out how many parts of a ratio are there.

7+4 = 11 parts

Then after finding the total parts, we know that the number of students must be a multiple of the total number of parts.

11 x 3 = 33

So, the total number of students is 33.

4 x 3 = 12 Boys

7 x 3 = 21 Girls.

Thank you.
