What three numbers have an average of 483?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 483. This means if we add these three numbers together and divide by 3, we should get 483.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 483 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 483 * 3 = x + y + z
- So, the sum of our three numbers should be: 1449
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1449.
Solution 1:
483, 483, 483
Verification:
(483 + 483 + 483) / 3 = 1449 / 3 ≈ 483
This solution is correct!
Solution 2:
483, 483, 483
Verification:
(483 + 483 + 483) / 3 = 1449 / 3 ≈ 483
This solution is correct!
Solution 3:
702, 469, 278
Verification:
(702 + 469 + 278) / 3 = 1449 / 3 ≈ 483
This solution is correct!
Solution 4:
448, 705, 296
Verification:
(448 + 705 + 296) / 3 = 1449 / 3 ≈ 483
This solution is correct!
Solution 5:
1390, 54, 5
Verification:
(1390 + 54 + 5) / 3 = 1449 / 3 ≈ 483
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 1449 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.
