What three numbers have an average of 502?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 502. This means if we add these three numbers together and divide by 3, we should get 502.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 502 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 502 * 3 = x + y + z
- So, the sum of our three numbers should be: 1506
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1506.
Solution 1:
502, 502, 502
Verification:
(502 + 502 + 502) / 3 = 1506 / 3 ≈ 502
This solution is correct!
Solution 2:
502, 502, 502
Verification:
(502 + 502 + 502) / 3 = 1506 / 3 ≈ 502
This solution is correct!
Solution 3:
355, 204, 947
Verification:
(355 + 204 + 947) / 3 = 1506 / 3 ≈ 502
This solution is correct!
Solution 4:
729, 169, 608
Verification:
(729 + 169 + 608) / 3 = 1506 / 3 ≈ 502
This solution is correct!
Solution 5:
754, 279, 473
Verification:
(754 + 279 + 473) / 3 = 1506 / 3 ≈ 502
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 1506 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.
