To find the average of a group of numbers, first you must know:
- The sum of all the numbers presented
- How many numbers are presented
In general knowledge, there are two steps.
First, you find the sum of the numbers presented.
Second, divide that sum by how many numbers are found in that group.
Let's have some examples!
Find the average of:
50, 100, 150, 200
Find the sum of those numbers:
Next, divide the sum by how many numbers are found. Therefore:
The average is 125.
Let's have a quiz:
1.) Find the average of 125, 250, and 500.
2.) Find the average of 10, 20, and 30.
3. Find the average of 150, 260, and 60.
