What three numbers have an average of 229?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 229. This means if we add these three numbers together and divide by 3, we should get 229.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 229 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 229 * 3 = x + y + z
- So, the sum of our three numbers should be: 687
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 687.
Solution 1:
229, 229, 229
Verification:
(229 + 229 + 229) / 3 = 687 / 3 ≈ 229
This solution is correct!
Solution 2:
229, 229, 229
Verification:
(229 + 229 + 229) / 3 = 687 / 3 ≈ 229
This solution is correct!
Solution 3:
325, 203, 159
Verification:
(325 + 203 + 159) / 3 = 687 / 3 ≈ 229
This solution is correct!
Solution 4:
630, 13, 44
Verification:
(630 + 13 + 44) / 3 = 687 / 3 ≈ 229
This solution is correct!
Solution 5:
10, 107, 570
Verification:
(10 + 107 + 570) / 3 = 687 / 3 ≈ 229
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 687 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.
