What three numbers have an average of 872?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 872. This means if we add these three numbers together and divide by 3, we should get 872.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 872 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 872 * 3 = x + y + z
- So, the sum of our three numbers should be: 2616
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2616.
Solution 1:
872, 872, 872
Verification:
(872 + 872 + 872) / 3 = 2616 / 3 ≈ 872
This solution is correct!
Solution 2:
872, 872, 872
Verification:
(872 + 872 + 872) / 3 = 2616 / 3 ≈ 872
This solution is correct!
Solution 3:
132, 1228, 1256
Verification:
(132 + 1228 + 1256) / 3 = 2616 / 3 ≈ 872
This solution is correct!
Solution 4:
1944, 112, 560
Verification:
(1944 + 112 + 560) / 3 = 2616 / 3 ≈ 872
This solution is correct!
Solution 5:
1991, 149, 476
Verification:
(1991 + 149 + 476) / 3 = 2616 / 3 ≈ 872
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 2616 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.
