Answer 2

Answer:

There are 35 boys in the class.

Step-by-step explanation:

This question can be solved as a rule of three.

In science class, the girl to boy ratio is 3 to 7.

This means that for each 10 students, 7 of them are boys and 3 are girls.

So if for 10 students, 7 of them are boys, how many are boys for 50?

7 boys - 10 students

x boys - 50 students

$10x = 7*50$

$10x = 350$

$x = 35$

There are 35 boys in the class.
