What three numbers have an average of 195?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 195. This means if we add these three numbers together and divide by 3, we should get 195.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 195 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 195 * 3 = x + y + z
- So, the sum of our three numbers should be: 585
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 585.
Solution 1:
195, 195, 195
Verification:
(195 + 195 + 195) / 3 = 585 / 3 ≈ 195
This solution is correct!
Solution 2:
195, 195, 195
Verification:
(195 + 195 + 195) / 3 = 585 / 3 ≈ 195
This solution is correct!
Solution 3:
319, 89, 177
Verification:
(319 + 89 + 177) / 3 = 585 / 3 ≈ 195
This solution is correct!
Solution 4:
312, 84, 189
Verification:
(312 + 84 + 189) / 3 = 585 / 3 ≈ 195
This solution is correct!
Solution 5:
582, 2, 1
Verification:
(582 + 2 + 1) / 3 = 585 / 3 ≈ 195
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 585 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.
