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:
157, 1269, 1085
Verification:
(157 + 1269 + 1085) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 4:
244, 2219, 48
Verification:
(244 + 2219 + 48) / 3 = 2511 / 3 ≈ 837
This solution is correct!
Solution 5:
1553, 275, 683
Verification:
(1553 + 275 + 683) / 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.
