What three numbers have an average of 784?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 784. This means if we add these three numbers together and divide by 3, we should get 784.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 784 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 784 * 3 = x + y + z
- So, the sum of our three numbers should be: 2352
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2352.
Solution 1:
784, 784, 784
Verification:
(784 + 784 + 784) / 3 = 2352 / 3 ≈ 784
This solution is correct!
Solution 2:
784, 784, 784
Verification:
(784 + 784 + 784) / 3 = 2352 / 3 ≈ 784
This solution is correct!
Solution 3:
587, 1394, 371
Verification:
(587 + 1394 + 371) / 3 = 2352 / 3 ≈ 784
This solution is correct!
Solution 4:
1477, 824, 51
Verification:
(1477 + 824 + 51) / 3 = 2352 / 3 ≈ 784
This solution is correct!
Solution 5:
586, 1050, 716
Verification:
(586 + 1050 + 716) / 3 = 2352 / 3 ≈ 784
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 2352 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.
