Liam test scores in math are 91, 67, 85, 83, 77, what is his average in math?

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
