What three numbers have an average of 537?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 537. This means if we add these three numbers together and divide by 3, we should get 537.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 537 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 537 * 3 = x + y + z
- So, the sum of our three numbers should be: 1611
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1611.
Solution 1:
537, 537, 537
Verification:
(537 + 537 + 537) / 3 = 1611 / 3 ≈ 537
This solution is correct!
Solution 2:
537, 537, 537
Verification:
(537 + 537 + 537) / 3 = 1611 / 3 ≈ 537
This solution is correct!
Solution 3:
1128, 444, 39
Verification:
(1128 + 444 + 39) / 3 = 1611 / 3 ≈ 537
This solution is correct!
Solution 4:
790, 31, 790
Verification:
(790 + 31 + 790) / 3 = 1611 / 3 ≈ 537
This solution is correct!
Solution 5:
1483, 15, 113
Verification:
(1483 + 15 + 113) / 3 = 1611 / 3 ≈ 537
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 1611 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.
