What three numbers have an average of 996?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 996. This means if we add these three numbers together and divide by 3, we should get 996.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 996 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 996 * 3 = x + y + z
- So, the sum of our three numbers should be: 2988
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2988.
Solution 1:
996, 996, 996
Verification:
(996 + 996 + 996) / 3 = 2988 / 3 ≈ 996
This solution is correct!
Solution 2:
996, 996, 996
Verification:
(996 + 996 + 996) / 3 = 2988 / 3 ≈ 996
This solution is correct!
Solution 3:
1271, 1349, 368
Verification:
(1271 + 1349 + 368) / 3 = 2988 / 3 ≈ 996
This solution is correct!
Solution 4:
2848, 35, 105
Verification:
(2848 + 35 + 105) / 3 = 2988 / 3 ≈ 996
This solution is correct!
Solution 5:
2328, 648, 12
Verification:
(2328 + 648 + 12) / 3 = 2988 / 3 ≈ 996
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 2988 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.
