What three numbers have an average of 999?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 999. This means if we add these three numbers together and divide by 3, we should get 999.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 999 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 999 * 3 = x + y + z
- So, the sum of our three numbers should be: 2997
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2997.
Solution 1:
999, 999, 999
Verification:
(999 + 999 + 999) / 3 = 2997 / 3 ≈ 999
This solution is correct!
Solution 2:
999, 999, 999
Verification:
(999 + 999 + 999) / 3 = 2997 / 3 ≈ 999
This solution is correct!
Solution 3:
532, 36, 2429
Verification:
(532 + 36 + 2429) / 3 = 2997 / 3 ≈ 999
This solution is correct!
Solution 4:
2837, 98, 62
Verification:
(2837 + 98 + 62) / 3 = 2997 / 3 ≈ 999
This solution is correct!
Solution 5:
2133, 91, 773
Verification:
(2133 + 91 + 773) / 3 = 2997 / 3 ≈ 999
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 2997 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.
