Mason brought 18 red pencils to school. He brought 4 times as many erasers with him. How many erasers did Mason bring to school?

Let M = how many erasers
18x4=M
M=42

No.

Do the arithmetic again.

18

x4
____
72

To find out how many erasers Mason brought to school, we need to use the information given in the question. It says that Mason brought 18 red pencils to school, and he brought 4 times as many erasers with him.

Let's use algebra to solve the problem. Let's represent the number of erasers Mason brought with the variable "M". According to the question, the number of erasers Mason brought is 4 times the number of red pencils, which is 18.

So we can write the equation: 4 * 18 = M

To find M, we simplify the equation. 4 * 18 equals 72.

Therefore, Mason brought 72 erasers to school.
