What three numbers have an average of 791?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 791. This means if we add these three numbers together and divide by 3, we should get 791.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 791 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 791 * 3 = x + y + z
- So, the sum of our three numbers should be: 2373
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2373.
Solution 1:
791, 791, 791
Verification:
(791 + 791 + 791) / 3 = 2373 / 3 ≈ 791
This solution is correct!
Solution 2:
791, 791, 791
Verification:
(791 + 791 + 791) / 3 = 2373 / 3 ≈ 791
This solution is correct!
Solution 3:
1557, 647, 169
Verification:
(1557 + 647 + 169) / 3 = 2373 / 3 ≈ 791
This solution is correct!
Solution 4:
542, 204, 1627
Verification:
(542 + 204 + 1627) / 3 = 2373 / 3 ≈ 791
This solution is correct!
Solution 5:
205, 1361, 807
Verification:
(205 + 1361 + 807) / 3 = 2373 / 3 ≈ 791
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 2373 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.
