What three numbers have an average of 185?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 185. This means if we add these three numbers together and divide by 3, we should get 185.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 185 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 185 * 3 = x + y + z
- So, the sum of our three numbers should be: 555
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 555.
Solution 1:
185, 185, 185
Verification:
(185 + 185 + 185) / 3 = 555 / 3 ≈ 185
This solution is correct!
Solution 2:
185, 185, 185
Verification:
(185 + 185 + 185) / 3 = 555 / 3 ≈ 185
This solution is correct!
Solution 3:
382, 96, 77
Verification:
(382 + 96 + 77) / 3 = 555 / 3 ≈ 185
This solution is correct!
Solution 4:
508, 24, 23
Verification:
(508 + 24 + 23) / 3 = 555 / 3 ≈ 185
This solution is correct!
Solution 5:
183, 237, 135
Verification:
(183 + 237 + 135) / 3 = 555 / 3 ≈ 185
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 555 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.
