80 is. ------------------------------------------- The mean average is calculated by adding up the numbers and dividing by how many there are: mean average = (80 + 60 + 70 + 110) ÷ 4 = 320 ÷ 4 = 80
80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110
For the values: 104, 80 the LCM is: 1040
80% is the same as 0.8 and 0.8*104 = 83.2
104 is 30% more than 80.
The average is 80.
