What three numbers have an average of 227?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 227. This means if we add these three numbers together and divide by 3, we should get 227.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 227 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 227 * 3 = x + y + z
- So, the sum of our three numbers should be: 681
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 681.
Solution 1:
227, 227, 227
Verification:
(227 + 227 + 227) / 3 = 681 / 3 ≈ 227
This solution is correct!
Solution 2:
227, 227, 227
Verification:
(227 + 227 + 227) / 3 = 681 / 3 ≈ 227
This solution is correct!
Solution 3:
408, 149, 124
Verification:
(408 + 149 + 124) / 3 = 681 / 3 ≈ 227
This solution is correct!
Solution 4:
158, 5, 518
Verification:
(158 + 5 + 518) / 3 = 681 / 3 ≈ 227
This solution is correct!
Solution 5:
256, 378, 47
Verification:
(256 + 378 + 47) / 3 = 681 / 3 ≈ 227
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 681 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.
