What three numbers have an average of 269?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 269. This means if we add these three numbers together and divide by 3, we should get 269.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 269 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 269 * 3 = x + y + z
- So, the sum of our three numbers should be: 807
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 807.
Solution 1:
269, 269, 269
Verification:
(269 + 269 + 269) / 3 = 807 / 3 ≈ 269
This solution is correct!
Solution 2:
269, 269, 269
Verification:
(269 + 269 + 269) / 3 = 807 / 3 ≈ 269
This solution is correct!
Solution 3:
196, 531, 80
Verification:
(196 + 531 + 80) / 3 = 807 / 3 ≈ 269
This solution is correct!
Solution 4:
610, 82, 115
Verification:
(610 + 82 + 115) / 3 = 807 / 3 ≈ 269
This solution is correct!
Solution 5:
44, 252, 511
Verification:
(44 + 252 + 511) / 3 = 807 / 3 ≈ 269
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 807 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.
