What three numbers have an average of 319?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 319. This means if we add these three numbers together and divide by 3, we should get 319.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 319 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 319 * 3 = x + y + z
- So, the sum of our three numbers should be: 957
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 957.
Solution 1:
319, 319, 319
Verification:
(319 + 319 + 319) / 3 = 957 / 3 ≈ 319
This solution is correct!
Solution 2:
319, 319, 319
Verification:
(319 + 319 + 319) / 3 = 957 / 3 ≈ 319
This solution is correct!
Solution 3:
918, 28, 11
Verification:
(918 + 28 + 11) / 3 = 957 / 3 ≈ 319
This solution is correct!
Solution 4:
174, 613, 170
Verification:
(174 + 613 + 170) / 3 = 957 / 3 ≈ 319
This solution is correct!
Solution 5:
386, 559, 12
Verification:
(386 + 559 + 12) / 3 = 957 / 3 ≈ 319
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 957 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.
