What three numbers have an average of 547?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 547. This means if we add these three numbers together and divide by 3, we should get 547.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 547 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 547 * 3 = x + y + z
- So, the sum of our three numbers should be: 1641
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1641.
Solution 1:
547, 547, 547
Verification:
(547 + 547 + 547) / 3 = 1641 / 3 ≈ 547
This solution is correct!
Solution 2:
547, 547, 547
Verification:
(547 + 547 + 547) / 3 = 1641 / 3 ≈ 547
This solution is correct!
Solution 3:
359, 136, 1146
Verification:
(359 + 136 + 1146) / 3 = 1641 / 3 ≈ 547
This solution is correct!
Solution 4:
128, 1490, 23
Verification:
(128 + 1490 + 23) / 3 = 1641 / 3 ≈ 547
This solution is correct!
Solution 5:
1166, 227, 248
Verification:
(1166 + 227 + 248) / 3 = 1641 / 3 ≈ 547
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 1641 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.
