    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

    Answer: 80.6

    Step-by-step explanation:

    91+67+85+83+77 = 403

    divide by 5 because we added 5 numbers

    403 ÷ 5 = 80.6

    so the test average is 80.6
