What three numbers have an average of 463?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 463. This means if we add these three numbers together and divide by 3, we should get 463.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 463 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 463 * 3 = x + y + z
- So, the sum of our three numbers should be: 1389
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1389.
Solution 1:
463, 463, 463
Verification:
(463 + 463 + 463) / 3 = 1389 / 3 ≈ 463
This solution is correct!
Solution 2:
463, 463, 463
Verification:
(463 + 463 + 463) / 3 = 1389 / 3 ≈ 463
This solution is correct!
Solution 3:
739, 86, 564
Verification:
(739 + 86 + 564) / 3 = 1389 / 3 ≈ 463
This solution is correct!
Solution 4:
39, 843, 507
Verification:
(39 + 843 + 507) / 3 = 1389 / 3 ≈ 463
This solution is correct!
Solution 5:
782, 185, 422
Verification:
(782 + 185 + 422) / 3 = 1389 / 3 ≈ 463
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 1389 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.
