What three numbers have an average of 511?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 511. This means if we add these three numbers together and divide by 3, we should get 511.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 511 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 511 * 3 = x + y + z
- So, the sum of our three numbers should be: 1533
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1533.
Solution 1:
511, 511, 511
Verification:
(511 + 511 + 511) / 3 = 1533 / 3 ≈ 511
This solution is correct!
Solution 2:
511, 511, 511
Verification:
(511 + 511 + 511) / 3 = 1533 / 3 ≈ 511
This solution is correct!
Solution 3:
720, 572, 241
Verification:
(720 + 572 + 241) / 3 = 1533 / 3 ≈ 511
This solution is correct!
Solution 4:
144, 94, 1295
Verification:
(144 + 94 + 1295) / 3 = 1533 / 3 ≈ 511
This solution is correct!
Solution 5:
1057, 119, 357
Verification:
(1057 + 119 + 357) / 3 = 1533 / 3 ≈ 511
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 1533 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.
