What three numbers have an average of 726?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 726. This means if we add these three numbers together and divide by 3, we should get 726.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 726 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 726 * 3 = x + y + z
- So, the sum of our three numbers should be: 2178
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2178.
Solution 1:
726, 726, 726
Verification:
(726 + 726 + 726) / 3 = 2178 / 3 ≈ 726
This solution is correct!
Solution 2:
726, 726, 726
Verification:
(726 + 726 + 726) / 3 = 2178 / 3 ≈ 726
This solution is correct!
Solution 3:
1301, 613, 264
Verification:
(1301 + 613 + 264) / 3 = 2178 / 3 ≈ 726
This solution is correct!
Solution 4:
2131, 23, 24
Verification:
(2131 + 23 + 24) / 3 = 2178 / 3 ≈ 726
This solution is correct!
Solution 5:
211, 1297, 670
Verification:
(211 + 1297 + 670) / 3 = 2178 / 3 ≈ 726
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 2178 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.
