Answer:

Explanation:

Ratios come in 3 forms: 2 to 3, 2:3, and 2/3, which means there are 2 girls for every 3 boys. I like to put it into a fraction form like this:

2 28

--------- = ---------

3 ?

The numerator is girls and the denominator is boys. How did 2 go to 28? x 14. What is 3 x 14? 42. So, this is the new fraction:

2 28

--------- = ---------

3 42

BUT, it asks for total number of students. What is 28 + 42? 70. So, there are 70 total students.

Answer:

I believe there are 70 students in the theater!

Explanation:

In the ratio 2:3 going to 28:? there is a pattern. You multiply 2 by 14 to get to 28, so if you multiply 3 by 14 you get 42. Add 42 to 28 for the total amount of students in class!

Have a nice night!
