What three numbers have an average of 847?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 847. This means if we add these three numbers together and divide by 3, we should get 847.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 847 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 847 * 3 = x + y + z
- So, the sum of our three numbers should be: 2541
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2541.
Solution 1:
847, 847, 847
Verification:
(847 + 847 + 847) / 3 = 2541 / 3 ≈ 847
This solution is correct!
Solution 2:
847, 847, 847
Verification:
(847 + 847 + 847) / 3 = 2541 / 3 ≈ 847
This solution is correct!
Solution 3:
236, 91, 2214
Verification:
(236 + 91 + 2214) / 3 = 2541 / 3 ≈ 847
This solution is correct!
Solution 4:
1323, 821, 397
Verification:
(1323 + 821 + 397) / 3 = 2541 / 3 ≈ 847
This solution is correct!
Solution 5:
1435, 336, 770
Verification:
(1435 + 336 + 770) / 3 = 2541 / 3 ≈ 847
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 2541 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.
