What three numbers have an average of 764?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 764. This means if we add these three numbers together and divide by 3, we should get 764.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 764 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 764 * 3 = x + y + z
- So, the sum of our three numbers should be: 2292
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2292.
Solution 1:
764, 764, 764
Verification:
(764 + 764 + 764) / 3 = 2292 / 3 ≈ 764
This solution is correct!
Solution 2:
764, 764, 764
Verification:
(764 + 764 + 764) / 3 = 2292 / 3 ≈ 764
This solution is correct!
Solution 3:
754, 1307, 231
Verification:
(754 + 1307 + 231) / 3 = 2292 / 3 ≈ 764
This solution is correct!
Solution 4:
1255, 72, 965
Verification:
(1255 + 72 + 965) / 3 = 2292 / 3 ≈ 764
This solution is correct!
Solution 5:
2217, 20, 55
Verification:
(2217 + 20 + 55) / 3 = 2292 / 3 ≈ 764
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 2292 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.
