What three numbers have an average of 204?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 204. This means if we add these three numbers together and divide by 3, we should get 204.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 204 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 204 * 3 = x + y + z
- So, the sum of our three numbers should be: 612
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 612.
Solution 1:
204, 204, 204
Verification:
(204 + 204 + 204) / 3 = 612 / 3 ≈ 204
This solution is correct!
Solution 2:
204, 204, 204
Verification:
(204 + 204 + 204) / 3 = 612 / 3 ≈ 204
This solution is correct!
Solution 3:
198, 316, 98
Verification:
(198 + 316 + 98) / 3 = 612 / 3 ≈ 204
This solution is correct!
Solution 4:
226, 206, 180
Verification:
(226 + 206 + 180) / 3 = 612 / 3 ≈ 204
This solution is correct!
Solution 5:
487, 112, 13
Verification:
(487 + 112 + 13) / 3 = 612 / 3 ≈ 204
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 612 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.
