What three numbers have an average of 497?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 497. This means if we add these three numbers together and divide by 3, we should get 497.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 497 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 497 * 3 = x + y + z
- So, the sum of our three numbers should be: 1491
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1491.
Solution 1:
497, 497, 497
Verification:
(497 + 497 + 497) / 3 = 1491 / 3 ≈ 497
This solution is correct!
Solution 2:
497, 497, 497
Verification:
(497 + 497 + 497) / 3 = 1491 / 3 ≈ 497
This solution is correct!
Solution 3:
432, 813, 246
Verification:
(432 + 813 + 246) / 3 = 1491 / 3 ≈ 497
This solution is correct!
Solution 4:
265, 1124, 102
Verification:
(265 + 1124 + 102) / 3 = 1491 / 3 ≈ 497
This solution is correct!
Solution 5:
463, 522, 506
Verification:
(463 + 522 + 506) / 3 = 1491 / 3 ≈ 497
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 1491 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.
