What three numbers have an average of 180?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 180. This means if we add these three numbers together and divide by 3, we should get 180.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 180 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 180 * 3 = x + y + z
- So, the sum of our three numbers should be: 540
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 540.
Solution 1:
180, 180, 180
Verification:
(180 + 180 + 180) / 3 = 540 / 3 ≈ 180
This solution is correct!
Solution 2:
180, 180, 180
Verification:
(180 + 180 + 180) / 3 = 540 / 3 ≈ 180
This solution is correct!
Solution 3:
338, 178, 24
Verification:
(338 + 178 + 24) / 3 = 540 / 3 ≈ 180
This solution is correct!
Solution 4:
506, 21, 13
Verification:
(506 + 21 + 13) / 3 = 540 / 3 ≈ 180
This solution is correct!
Solution 5:
340, 157, 43
Verification:
(340 + 157 + 43) / 3 = 540 / 3 ≈ 180
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 540 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.
