What three numbers have an average of 797?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 797. This means if we add these three numbers together and divide by 3, we should get 797.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 797 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 797 * 3 = x + y + z
- So, the sum of our three numbers should be: 2391
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2391.
Solution 1:
797, 797, 797
Verification:
(797 + 797 + 797) / 3 = 2391 / 3 ≈ 797
This solution is correct!
Solution 2:
797, 797, 797
Verification:
(797 + 797 + 797) / 3 = 2391 / 3 ≈ 797
This solution is correct!
Solution 3:
2169, 18, 204
Verification:
(2169 + 18 + 204) / 3 = 2391 / 3 ≈ 797
This solution is correct!
Solution 4:
685, 360, 1346
Verification:
(685 + 360 + 1346) / 3 = 2391 / 3 ≈ 797
This solution is correct!
Solution 5:
738, 909, 744
Verification:
(738 + 909 + 744) / 3 = 2391 / 3 ≈ 797
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 2391 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.
