What three numbers have an average of 283?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 283. This means if we add these three numbers together and divide by 3, we should get 283.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 283 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 283 * 3 = x + y + z
- So, the sum of our three numbers should be: 849
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 849.
Solution 1:
283, 283, 283
Verification:
(283 + 283 + 283) / 3 = 849 / 3 ≈ 283
This solution is correct!
Solution 2:
283, 283, 283
Verification:
(283 + 283 + 283) / 3 = 849 / 3 ≈ 283
This solution is correct!
Solution 3:
158, 288, 403
Verification:
(158 + 288 + 403) / 3 = 849 / 3 ≈ 283
This solution is correct!
Solution 4:
749, 73, 27
Verification:
(749 + 73 + 27) / 3 = 849 / 3 ≈ 283
This solution is correct!
Solution 5:
509, 280, 60
Verification:
(509 + 280 + 60) / 3 = 849 / 3 ≈ 283
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 849 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.
