What three numbers have an average of 906?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 906. This means if we add these three numbers together and divide by 3, we should get 906.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 906 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 906 * 3 = x + y + z
- So, the sum of our three numbers should be: 2718
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2718.
Solution 1:
906, 906, 906
Verification:
(906 + 906 + 906) / 3 = 2718 / 3 ≈ 906
This solution is correct!
Solution 2:
906, 906, 906
Verification:
(906 + 906 + 906) / 3 = 2718 / 3 ≈ 906
This solution is correct!
Solution 3:
2376, 151, 191
Verification:
(2376 + 151 + 191) / 3 = 2718 / 3 ≈ 906
This solution is correct!
Solution 4:
1703, 800, 215
Verification:
(1703 + 800 + 215) / 3 = 2718 / 3 ≈ 906
This solution is correct!
Solution 5:
2176, 11, 531
Verification:
(2176 + 11 + 531) / 3 = 2718 / 3 ≈ 906
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 2718 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.
