c

B

Step-by-step explanation:

If there are 28 students and 4/7 are girls we can easily find out how many are girls because 28 divides by seven into a whole number. If we divide 28 by 7 we get 4. And that means that each 1/7 of the class is 4 students. So if we take 4 students times 4, for the 4/7 of the classroom were trying to find, we get 16. Or simple way, just multiply 28/1 times 4/7. Either way.
