Answer:

80.6 or 81

Step-by-step explanation:

The average is another word for the mean. To find the mean you must add all the numbers then divide by how many numbers there are.

91+67+85+83+77= 403

403/5= 80.6

The answer in decimal form is 80.6 and the number rounded is 81. So Liam's average in math is an 80.6
