There are 24 boys in a class, and 2/3 of the students in the class are boys. How many students are girls ?

12 girls.

Step-by-step explanation:

24 ÷ 2 = 12

(This is divided to find out 1 part of the whole class as ⅓)

⅓ = 12

1 (whole) take away ⅔ = ⅓

Since ⅔ + ⅓ = 1

⅓ = fraction of girls in class

1 part = 12

So ⅓ = 12 girls out of 36 total students

Hope this helps. :)
