How to find the average of a number
To find the average of a set of numbers, add all of the numbers together and divide by the total number of numbers in the set. For example, to find the average of 2, 4, and 6, add them together (2 + 4 + 6 = 12) and then divide by the total number of numbers (3):
average = 12 ÷ 3
average = 4
So the average of 2, 4, and 6 is 4.
To find the average of a set of numbers, follow these steps:
1. Add up all the numbers in the set.
2. Count the total number of numbers in the set.
3. Divide the sum of the numbers by the total count.
Mathematically, it can be expressed as:
Average = (Sum of all numbers) / (Total count of numbers)
Let's go through an example:
Example:
Suppose we have a set of numbers: 5, 8, 3, 2, 9
Step 1: Add up all the numbers:
5 + 8 + 3 + 2 + 9 = 27
Step 2: Count the total number of numbers:
There are 5 numbers in the set.
Step 3: Divide the sum of the numbers by the total count:
27 / 5 = 5.4
Therefore, the average of the given set of numbers is 5.4.
