What three numbers have an average of 767?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 767. This means if we add these three numbers together and divide by 3, we should get 767.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 767 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 767 * 3 = x + y + z
- So, the sum of our three numbers should be: 2301
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2301.
Solution 1:
767, 767, 767
Verification:
(767 + 767 + 767) / 3 = 2301 / 3 ≈ 767
This solution is correct!
Solution 2:
767, 767, 767
Verification:
(767 + 767 + 767) / 3 = 2301 / 3 ≈ 767
This solution is correct!
Solution 3:
1579, 28, 694
Verification:
(1579 + 28 + 694) / 3 = 2301 / 3 ≈ 767
This solution is correct!
Solution 4:
143, 616, 1542
Verification:
(143 + 616 + 1542) / 3 = 2301 / 3 ≈ 767
This solution is correct!
Solution 5:
246, 538, 1517
Verification:
(246 + 538 + 1517) / 3 = 2301 / 3 ≈ 767
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 2301 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.
