What three numbers have an average of 446?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 446. This means if we add these three numbers together and divide by 3, we should get 446.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 446 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 446 * 3 = x + y + z
- So, the sum of our three numbers should be: 1338
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1338.
Solution 1:
446, 446, 446
Verification:
(446 + 446 + 446) / 3 = 1338 / 3 ≈ 446
This solution is correct!
Solution 2:
446, 446, 446
Verification:
(446 + 446 + 446) / 3 = 1338 / 3 ≈ 446
This solution is correct!
Solution 3:
361, 779, 198
Verification:
(361 + 779 + 198) / 3 = 1338 / 3 ≈ 446
This solution is correct!
Solution 4:
864, 428, 46
Verification:
(864 + 428 + 46) / 3 = 1338 / 3 ≈ 446
This solution is correct!
Solution 5:
1254, 21, 63
Verification:
(1254 + 21 + 63) / 3 = 1338 / 3 ≈ 446
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 1338 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.
