What three numbers have an average of 168?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 168. This means if we add these three numbers together and divide by 3, we should get 168.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 168 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 168 * 3 = x + y + z
- So, the sum of our three numbers should be: 504
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 504.
Solution 1:
168, 168, 168
Verification:
(168 + 168 + 168) / 3 = 504 / 3 ≈ 168
This solution is correct!
Solution 2:
168, 168, 168
Verification:
(168 + 168 + 168) / 3 = 504 / 3 ≈ 168
This solution is correct!
Solution 3:
332, 160, 12
Verification:
(332 + 160 + 12) / 3 = 504 / 3 ≈ 168
This solution is correct!
Solution 4:
364, 54, 86
Verification:
(364 + 54 + 86) / 3 = 504 / 3 ≈ 168
This solution is correct!
Solution 5:
410, 30, 64
Verification:
(410 + 30 + 64) / 3 = 504 / 3 ≈ 168
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 504 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.
