What three numbers have an average of 199?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 199. This means if we add these three numbers together and divide by 3, we should get 199.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 199 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 199 * 3 = x + y + z
- So, the sum of our three numbers should be: 597
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 597.
Solution 1:
199, 199, 199
Verification:
(199 + 199 + 199) / 3 = 597 / 3 ≈ 199
This solution is correct!
Solution 2:
199, 199, 199
Verification:
(199 + 199 + 199) / 3 = 597 / 3 ≈ 199
This solution is correct!
Solution 3:
381, 90, 126
Verification:
(381 + 90 + 126) / 3 = 597 / 3 ≈ 199
This solution is correct!
Solution 4:
223, 368, 6
Verification:
(223 + 368 + 6) / 3 = 597 / 3 ≈ 199
This solution is correct!
Solution 5:
278, 194, 125
Verification:
(278 + 194 + 125) / 3 = 597 / 3 ≈ 199
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 597 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.
