What three numbers have an average of 22?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 22. This means if we add these three numbers together and divide by 3, we should get 22.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 22 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 22 * 3 = x + y + z
- So, the sum of our three numbers should be: 66
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 66.
Solution 1:
22, 22, 22
Verification:
(22 + 22 + 22) / 3 = 66 / 3 ≈ 22
This solution is correct!
Solution 2:
22, 22, 22
Verification:
(22 + 22 + 22) / 3 = 66 / 3 ≈ 22
This solution is correct!
Solution 3:
30, 6, 30
Verification:
(30 + 6 + 30) / 3 = 66 / 3 ≈ 22
This solution is correct!
Solution 4:
57, 8, 1
Verification:
(57 + 8 + 1) / 3 = 66 / 3 ≈ 22
This solution is correct!
Solution 5:
13, 38, 15
Verification:
(13 + 38 + 15) / 3 = 66 / 3 ≈ 22
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 66 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
