Answer 1

`(3)/(4)x=21`

Explanation:

21 students like pizza which is the same as 3/4 of the class like pizza. The total amount of students in the class is x so 3/4 of x (or the class like pizza).

Therefore you get this equation:

`(3)/(4)x=21`

Next, you divide 21 by 3/4, and 3/4x divided by 3/4 so you get..

`(3)/(4)x/(3)/(4) =21/(3)/(4)`

x=21*(4/3)=28
