It is 79 by adding them up and then dividing the sum by 6
(78 + 56)/2 = 67
The average is 56.
(100 + 86 + 78)/3 = 88
78 30 x 2.6 = 78 CHECK: 100% of 30 = 30 200% of 30 = 60 10% of 30 = 3 60% of 30 = 18 200% + 60% = 60 + 18 = 78 Simply divide 30 by 100, to find 1% and then multiply by 260, to find 260%, which is 78
78 = 60% 78/6 = 10% 780/6 = 100% = 130 Check: 130 x 0.6 = 78
(78 + 56)/2 = 67
The average is 56.

To get an average, add the numbers together and divide by how many numbers there are.... 33 + 34 + 78 + 56 = 201. 201 / 4 = 50.25
(100 + 86 + 78)/3 = 88
