What three numbers have an average of 701?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 701. This means if we add these three numbers together and divide by 3, we should get 701.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 701 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 701 * 3 = x + y + z
- So, the sum of our three numbers should be: 2103
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2103.
Solution 1:
701, 701, 701
Verification:
(701 + 701 + 701) / 3 = 2103 / 3 ≈ 701
This solution is correct!
Solution 2:
701, 701, 701
Verification:
(701 + 701 + 701) / 3 = 2103 / 3 ≈ 701
This solution is correct!
Solution 3:
1077, 457, 569
Verification:
(1077 + 457 + 569) / 3 = 2103 / 3 ≈ 701
This solution is correct!
Solution 4:
1738, 184, 181
Verification:
(1738 + 184 + 181) / 3 = 2103 / 3 ≈ 701
This solution is correct!
Solution 5:
1909, 74, 120
Verification:
(1909 + 74 + 120) / 3 = 2103 / 3 ≈ 701
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 2103 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.
