What three numbers have an average of 271?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 271. This means if we add these three numbers together and divide by 3, we should get 271.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 271 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 271 * 3 = x + y + z
- So, the sum of our three numbers should be: 813
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 813.
Solution 1:
271, 271, 271
Verification:
(271 + 271 + 271) / 3 = 813 / 3 ≈ 271
This solution is correct!
Solution 2:
271, 271, 271
Verification:
(271 + 271 + 271) / 3 = 813 / 3 ≈ 271
This solution is correct!
Solution 3:
473, 308, 32
Verification:
(473 + 308 + 32) / 3 = 813 / 3 ≈ 271
This solution is correct!
Solution 4:
429, 252, 132
Verification:
(429 + 252 + 132) / 3 = 813 / 3 ≈ 271
This solution is correct!
Solution 5:
488, 14, 311
Verification:
(488 + 14 + 311) / 3 = 813 / 3 ≈ 271
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 813 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.
