What three numbers have an average of 177?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 177. This means if we add these three numbers together and divide by 3, we should get 177.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 177 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 177 * 3 = x + y + z
- So, the sum of our three numbers should be: 531
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 531.
Solution 1:
177, 177, 177
Verification:
(177 + 177 + 177) / 3 = 531 / 3 ≈ 177
This solution is correct!
Solution 2:
177, 177, 177
Verification:
(177 + 177 + 177) / 3 = 531 / 3 ≈ 177
This solution is correct!
Solution 3:
76, 396, 59
Verification:
(76 + 396 + 59) / 3 = 531 / 3 ≈ 177
This solution is correct!
Solution 4:
490, 13, 28
Verification:
(490 + 13 + 28) / 3 = 531 / 3 ≈ 177
This solution is correct!
Solution 5:
121, 98, 312
Verification:
(121 + 98 + 312) / 3 = 531 / 3 ≈ 177
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 531 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.
