What three numbers have an average of 519?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 519. This means if we add these three numbers together and divide by 3, we should get 519.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 519 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 519 * 3 = x + y + z
- So, the sum of our three numbers should be: 1557
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1557.
Solution 1:
519, 519, 519
Verification:
(519 + 519 + 519) / 3 = 1557 / 3 ≈ 519
This solution is correct!
Solution 2:
519, 519, 519
Verification:
(519 + 519 + 519) / 3 = 1557 / 3 ≈ 519
This solution is correct!
Solution 3:
1201, 110, 246
Verification:
(1201 + 110 + 246) / 3 = 1557 / 3 ≈ 519
This solution is correct!
Solution 4:
1046, 249, 262
Verification:
(1046 + 249 + 262) / 3 = 1557 / 3 ≈ 519
This solution is correct!
Solution 5:
253, 28, 1276
Verification:
(253 + 28 + 1276) / 3 = 1557 / 3 ≈ 519
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 1557 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.
