What three numbers have an average of 117?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 117. This means if we add these three numbers together and divide by 3, we should get 117.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 117 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 117 * 3 = x + y + z
- So, the sum of our three numbers should be: 351
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 351.
Solution 1:
117, 117, 117
Verification:
(117 + 117 + 117) / 3 = 351 / 3 ≈ 117
This solution is correct!
Solution 2:
117, 117, 117
Verification:
(117 + 117 + 117) / 3 = 351 / 3 ≈ 117
This solution is correct!
Solution 3:
283, 56, 12
Verification:
(283 + 56 + 12) / 3 = 351 / 3 ≈ 117
This solution is correct!
Solution 4:
308, 18, 25
Verification:
(308 + 18 + 25) / 3 = 351 / 3 ≈ 117
This solution is correct!
Solution 5:
293, 13, 45
Verification:
(293 + 13 + 45) / 3 = 351 / 3 ≈ 117
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 351 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.
