What three numbers have an average of 178?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 178. This means if we add these three numbers together and divide by 3, we should get 178.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 178 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 178 * 3 = x + y + z
- So, the sum of our three numbers should be: 534
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 534.
Solution 1:
178, 178, 178
Verification:
(178 + 178 + 178) / 3 = 534 / 3 ≈ 178
This solution is correct!
Solution 2:
178, 178, 178
Verification:
(178 + 178 + 178) / 3 = 534 / 3 ≈ 178
This solution is correct!
Solution 3:
187, 325, 22
Verification:
(187 + 325 + 22) / 3 = 534 / 3 ≈ 178
This solution is correct!
Solution 4:
509, 17, 8
Verification:
(509 + 17 + 8) / 3 = 534 / 3 ≈ 178
This solution is correct!
Solution 5:
329, 117, 88
Verification:
(329 + 117 + 88) / 3 = 534 / 3 ≈ 178
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 534 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.
