What three numbers have an average of 418?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 418. This means if we add these three numbers together and divide by 3, we should get 418.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 418 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 418 * 3 = x + y + z
- So, the sum of our three numbers should be: 1254
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1254.
Solution 1:
418, 418, 418
Verification:
(418 + 418 + 418) / 3 = 1254 / 3 ≈ 418
This solution is correct!
Solution 2:
418, 418, 418
Verification:
(418 + 418 + 418) / 3 = 1254 / 3 ≈ 418
This solution is correct!
Solution 3:
237, 273, 744
Verification:
(237 + 273 + 744) / 3 = 1254 / 3 ≈ 418
This solution is correct!
Solution 4:
732, 494, 28
Verification:
(732 + 494 + 28) / 3 = 1254 / 3 ≈ 418
This solution is correct!
Solution 5:
600, 109, 545
Verification:
(600 + 109 + 545) / 3 = 1254 / 3 ≈ 418
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 1254 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.
