What three numbers have an average of 852?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 852. This means if we add these three numbers together and divide by 3, we should get 852.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 852 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 852 * 3 = x + y + z
- So, the sum of our three numbers should be: 2556
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2556.
Solution 1:
852, 852, 852
Verification:
(852 + 852 + 852) / 3 = 2556 / 3 ≈ 852
This solution is correct!
Solution 2:
852, 852, 852
Verification:
(852 + 852 + 852) / 3 = 2556 / 3 ≈ 852
This solution is correct!
Solution 3:
1133, 931, 492
Verification:
(1133 + 931 + 492) / 3 = 2556 / 3 ≈ 852
This solution is correct!
Solution 4:
849, 1398, 309
Verification:
(849 + 1398 + 309) / 3 = 2556 / 3 ≈ 852
This solution is correct!
Solution 5:
682, 1820, 54
Verification:
(682 + 1820 + 54) / 3 = 2556 / 3 ≈ 852
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 2556 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.
