What three numbers have an average of 313?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 313. This means if we add these three numbers together and divide by 3, we should get 313.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 313 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 313 * 3 = x + y + z
- So, the sum of our three numbers should be: 939
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 939.
Solution 1:
313, 313, 313
Verification:
(313 + 313 + 313) / 3 = 939 / 3 ≈ 313
This solution is correct!
Solution 2:
313, 313, 313
Verification:
(313 + 313 + 313) / 3 = 939 / 3 ≈ 313
This solution is correct!
Solution 3:
292, 614, 33
Verification:
(292 + 614 + 33) / 3 = 939 / 3 ≈ 313
This solution is correct!
Solution 4:
259, 143, 537
Verification:
(259 + 143 + 537) / 3 = 939 / 3 ≈ 313
This solution is correct!
Solution 5:
37, 490, 412
Verification:
(37 + 490 + 412) / 3 = 939 / 3 ≈ 313
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 939 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.
