Working out the average
You learn to work out the average of a row of numbers by adding and dividing.
How to work it out
- To work out the average, first add all the numbers together.
- Then divide that total by how many numbers there were.
6, 8 and 10
- First add all the numbers: 6 + 8 + 10 = 24.
- Count how many numbers there are: that is 3.
- Divide the total by the number of numbers: 24 ÷ 3 = 8.
- The average is 8.
