What three numbers have an average of 553?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 553. This means if we add these three numbers together and divide by 3, we should get 553.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 553 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 553 * 3 = x + y + z
- So, the sum of our three numbers should be: 1659
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1659.
Solution 1:
553, 553, 553
Verification:
(553 + 553 + 553) / 3 = 1659 / 3 ≈ 553
This solution is correct!
Solution 2:
553, 553, 553
Verification:
(553 + 553 + 553) / 3 = 1659 / 3 ≈ 553
This solution is correct!
Solution 3:
1576, 49, 34
Verification:
(1576 + 49 + 34) / 3 = 1659 / 3 ≈ 553
This solution is correct!
Solution 4:
514, 92, 1053
Verification:
(514 + 92 + 1053) / 3 = 1659 / 3 ≈ 553
This solution is correct!
Solution 5:
1254, 113, 292
Verification:
(1254 + 113 + 292) / 3 = 1659 / 3 ≈ 553
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 1659 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.
