What three numbers have an average of 132?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 132. This means if we add these three numbers together and divide by 3, we should get 132.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 132 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 132 * 3 = x + y + z
- So, the sum of our three numbers should be: 396
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 396.
Solution 1:
132, 132, 132
Verification:
(132 + 132 + 132) / 3 = 396 / 3 ≈ 132
This solution is correct!
Solution 2:
132, 132, 132
Verification:
(132 + 132 + 132) / 3 = 396 / 3 ≈ 132
This solution is correct!
Solution 3:
154, 122, 120
Verification:
(154 + 122 + 120) / 3 = 396 / 3 ≈ 132
This solution is correct!
Solution 4:
191, 46, 159
Verification:
(191 + 46 + 159) / 3 = 396 / 3 ≈ 132
This solution is correct!
Solution 5:
362, 26, 8
Verification:
(362 + 26 + 8) / 3 = 396 / 3 ≈ 132
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 396 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.
