What three numbers have an average of 198?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 198. This means if we add these three numbers together and divide by 3, we should get 198.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 198 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 198 * 3 = x + y + z
- So, the sum of our three numbers should be: 594
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 594.
Solution 1:
198, 198, 198
Verification:
(198 + 198 + 198) / 3 = 594 / 3 ≈ 198
This solution is correct!
Solution 2:
198, 198, 198
Verification:
(198 + 198 + 198) / 3 = 594 / 3 ≈ 198
This solution is correct!
Solution 3:
133, 185, 276
Verification:
(133 + 185 + 276) / 3 = 594 / 3 ≈ 198
This solution is correct!
Solution 4:
81, 328, 185
Verification:
(81 + 328 + 185) / 3 = 594 / 3 ≈ 198
This solution is correct!
Solution 5:
5, 241, 348
Verification:
(5 + 241 + 348) / 3 = 594 / 3 ≈ 198
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 594 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.
