Molly played an online game three times. Her scores were 5.5, -3.6, and 12.8. What was her average score for three games?

Ivahew [28]

In order to find the solution you must calculate the mean, or the average by adding the numbers together and dividing by how many numbers there are.

5.5 + -3.6 + 12.8 = 14.7

14.7 ÷ 3 = 4.9

4.9 is Molly's average score.
