What three numbers have an average of 228?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 228. This means if we add these three numbers together and divide by 3, we should get 228.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 228 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 228 * 3 = x + y + z
- So, the sum of our three numbers should be: 684
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 684.
Solution 1:
228, 228, 228
Verification:
(228 + 228 + 228) / 3 = 684 / 3 ≈ 228
This solution is correct!
Solution 2:
228, 228, 228
Verification:
(228 + 228 + 228) / 3 = 684 / 3 ≈ 228
This solution is correct!
Solution 3:
338, 63, 283
Verification:
(338 + 63 + 283) / 3 = 684 / 3 ≈ 228
This solution is correct!
Solution 4:
453, 43, 188
Verification:
(453 + 43 + 188) / 3 = 684 / 3 ≈ 228
This solution is correct!
Solution 5:
299, 362, 23
Verification:
(299 + 362 + 23) / 3 = 684 / 3 ≈ 228
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 684 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.
