Question

In Mr. Peter's class, 75% of the students have a pet. There are 15 students with pets in the class. How many total students are in the class?

Answer 1

20 Students

Step-by-step explanation:

Let the total number of students in the class = x

Number of students that have pets = 15

Percentage of students that have pets = 75%

Therefore:

`75\%\text{ of x=15}`

We then solve for x.

`\begin{gathered} (75)/(100)* x=15 \\ 0.75x=15 \\ x=(15)/(0.75) \\ x=20 \end{gathered}`

We have 20 students in total in the class.
