What three numbers have an average of 901?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 901. This means if we add these three numbers together and divide by 3, we should get 901.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 901 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 901 * 3 = x + y + z
- So, the sum of our three numbers should be: 2703
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2703.
Solution 1:
901, 901, 901
Verification:
(901 + 901 + 901) / 3 = 2703 / 3 ≈ 901
This solution is correct!
Solution 2:
901, 901, 901
Verification:
(901 + 901 + 901) / 3 = 2703 / 3 ≈ 901
This solution is correct!
Solution 3:
2446, 50, 207
Verification:
(2446 + 50 + 207) / 3 = 2703 / 3 ≈ 901
This solution is correct!
Solution 4:
1404, 474, 825
Verification:
(1404 + 474 + 825) / 3 = 2703 / 3 ≈ 901
This solution is correct!
Solution 5:
1174, 723, 806
Verification:
(1174 + 723 + 806) / 3 = 2703 / 3 ≈ 901
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 2703 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.
