What three numbers have an average of 707?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 707. This means if we add these three numbers together and divide by 3, we should get 707.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 707 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 707 * 3 = x + y + z
- So, the sum of our three numbers should be: 2121
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2121.
Solution 1:
707, 707, 707
Verification:
(707 + 707 + 707) / 3 = 2121 / 3 ≈ 707
This solution is correct!
Solution 2:
707, 707, 707
Verification:
(707 + 707 + 707) / 3 = 2121 / 3 ≈ 707
This solution is correct!
Solution 3:
1192, 365, 564
Verification:
(1192 + 365 + 564) / 3 = 2121 / 3 ≈ 707
This solution is correct!
Solution 4:
1561, 176, 384
Verification:
(1561 + 176 + 384) / 3 = 2121 / 3 ≈ 707
This solution is correct!
Solution 5:
1754, 329, 38
Verification:
(1754 + 329 + 38) / 3 = 2121 / 3 ≈ 707
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 2121 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.
