What three numbers have an average of 838?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 838. This means if we add these three numbers together and divide by 3, we should get 838.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 838 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 838 * 3 = x + y + z
- So, the sum of our three numbers should be: 2514
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2514.
Solution 1:
838, 838, 838
Verification:
(838 + 838 + 838) / 3 = 2514 / 3 ≈ 838
This solution is correct!
Solution 2:
838, 838, 838
Verification:
(838 + 838 + 838) / 3 = 2514 / 3 ≈ 838
This solution is correct!
Solution 3:
2422, 17, 75
Verification:
(2422 + 17 + 75) / 3 = 2514 / 3 ≈ 838
This solution is correct!
Solution 4:
445, 405, 1664
Verification:
(445 + 405 + 1664) / 3 = 2514 / 3 ≈ 838
This solution is correct!
Solution 5:
2374, 79, 61
Verification:
(2374 + 79 + 61) / 3 = 2514 / 3 ≈ 838
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 2514 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.
