What three numbers have an average of 816?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 816. This means if we add these three numbers together and divide by 3, we should get 816.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 816 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 816 * 3 = x + y + z
- So, the sum of our three numbers should be: 2448
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2448.
Solution 1:
816, 816, 816
Verification:
(816 + 816 + 816) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 2:
816, 816, 816
Verification:
(816 + 816 + 816) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 3:
2066, 35, 347
Verification:
(2066 + 35 + 347) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 4:
2010, 207, 231
Verification:
(2010 + 207 + 231) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 5:
598, 939, 911
Verification:
(598 + 939 + 911) / 3 = 2448 / 3 ≈ 816
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 2448 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.
