What three numbers have an average of 493?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 493. This means if we add these three numbers together and divide by 3, we should get 493.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 493 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 493 * 3 = x + y + z
- So, the sum of our three numbers should be: 1479
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1479.
Solution 1:
493, 493, 493
Verification:
(493 + 493 + 493) / 3 = 1479 / 3 ≈ 493
This solution is correct!
Solution 2:
493, 493, 493
Verification:
(493 + 493 + 493) / 3 = 1479 / 3 ≈ 493
This solution is correct!
Solution 3:
635, 260, 584
Verification:
(635 + 260 + 584) / 3 = 1479 / 3 ≈ 493
This solution is correct!
Solution 4:
822, 58, 599
Verification:
(822 + 58 + 599) / 3 = 1479 / 3 ≈ 493
This solution is correct!
Solution 5:
879, 584, 16
Verification:
(879 + 584 + 16) / 3 = 1479 / 3 ≈ 493
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 1479 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.
