Question

One-tenth of the students in Mr. Albert's class

had perfect attendance. If 3 students had per-
fect attendance, how many students are in the
class?

Answer 1

Answer: 30

Step-by-step explanation: Lets assume the number of students in the class is x... then x/10 = 3 or x= 30

Answer 2

30 students

Explanation:

Let's use algebra to solve this problem.

Let "x" represent the total number of students in Mr. Albert's class.

We are given that one-tenth of the students had perfect attendance, and we know that 3 students had perfect attendance.

So, we can write the equation:

`\sf (1)/(10)* x = 3`

Now, to find the total number of students (x), we can solve for x by multiplying both sides of the equation by 10:

`\sf (1)/(10)* x * 10 = 3* 10`

`\sf x = 30`

So, there are 30 students in Mr. Albert's class.
