What three numbers have an average of 837?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 837. This means if we add these three numbers together and divide by 3, we should get 837.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 837 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 837 * 3 = x + y + z
- So, the sum of our three numbers should be: 2511
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2511.
Solution 1:
837, 837, 837
Verification:
(837 + 837 + 837) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 2:
837, 837, 837
Verification:
(837 + 837 + 837) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 3:
2410, 43, 58
Verification:
(2410 + 43 + 58) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 4:
1894, 1, 616
Verification:
(1894 + 1 + 616) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 5:
1805, 498, 208
Verification:
(1805 + 498 + 208) / 3 = 2511 / 3 ≈ 837
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 2511 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.
