What three numbers have an average of 506?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 506. This means if we add these three numbers together and divide by 3, we should get 506.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 506 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 506 * 3 = x + y + z
- So, the sum of our three numbers should be: 1518
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1518.
Solution 1:
506, 506, 506
Verification:
(506 + 506 + 506) / 3 = 1518 / 3 ≈ 506
This solution is correct!
Solution 2:
506, 506, 506
Verification:
(506 + 506 + 506) / 3 = 1518 / 3 ≈ 506
This solution is correct!
Solution 3:
545, 829, 144
Verification:
(545 + 829 + 144) / 3 = 1518 / 3 ≈ 506
This solution is correct!
Solution 4:
404, 486, 628
Verification:
(404 + 486 + 628) / 3 = 1518 / 3 ≈ 506
This solution is correct!
Solution 5:
798, 660, 60
Verification:
(798 + 660 + 60) / 3 = 1518 / 3 ≈ 506
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 1518 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.
