What three numbers have an average of 568?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 568. This means if we add these three numbers together and divide by 3, we should get 568.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 568 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 568 * 3 = x + y + z
- So, the sum of our three numbers should be: 1704
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1704.
Solution 1:
568, 568, 568
Verification:
(568 + 568 + 568) / 3 = 1704 / 3 ≈ 568
This solution is correct!
Solution 2:
568, 568, 568
Verification:
(568 + 568 + 568) / 3 = 1704 / 3 ≈ 568
This solution is correct!
Solution 3:
705, 664, 335
Verification:
(705 + 664 + 335) / 3 = 1704 / 3 ≈ 568
This solution is correct!
Solution 4:
874, 678, 152
Verification:
(874 + 678 + 152) / 3 = 1704 / 3 ≈ 568
This solution is correct!
Solution 5:
1404, 289, 11
Verification:
(1404 + 289 + 11) / 3 = 1704 / 3 ≈ 568
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 1704 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.
