What three numbers have an average of 181?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 181. This means if we add these three numbers together and divide by 3, we should get 181.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 181 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 181 * 3 = x + y + z
- So, the sum of our three numbers should be: 543
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 543.
Solution 1:
181, 181, 181
Verification:
(181 + 181 + 181) / 3 = 543 / 3 ≈ 181
This solution is correct!
Solution 2:
181, 181, 181
Verification:
(181 + 181 + 181) / 3 = 543 / 3 ≈ 181
This solution is correct!
Solution 3:
190, 305, 48
Verification:
(190 + 305 + 48) / 3 = 543 / 3 ≈ 181
This solution is correct!
Solution 4:
65, 393, 85
Verification:
(65 + 393 + 85) / 3 = 543 / 3 ≈ 181
This solution is correct!
Solution 5:
252, 93, 198
Verification:
(252 + 93 + 198) / 3 = 543 / 3 ≈ 181
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 543 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.
