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:
373, 1247, 828
Verification:
(373 + 1247 + 828) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 4:
310, 633, 1505
Verification:
(310 + 633 + 1505) / 3 = 2448 / 3 ≈ 816
This solution is correct!
Solution 5:
1191, 315, 942
Verification:
(1191 + 315 + 942) / 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.
