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
[tex]10x = 7*50[/tex]
[tex]10x = 350[/tex]
[tex]x = 35[/tex]
There are 35 boys in the class.
