What three numbers have an average of 466?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 466. This means if we add these three numbers together and divide by 3, we should get 466.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 466 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 466 * 3 = x + y + z
- So, the sum of our three numbers should be: 1398
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1398.
Solution 1:
466, 466, 466
Verification:
(466 + 466 + 466) / 3 = 1398 / 3 ≈ 466
This solution is correct!
Solution 2:
466, 466, 466
Verification:
(466 + 466 + 466) / 3 = 1398 / 3 ≈ 466
This solution is correct!
Solution 3:
990, 129, 279
Verification:
(990 + 129 + 279) / 3 = 1398 / 3 ≈ 466
This solution is correct!
Solution 4:
1020, 246, 132
Verification:
(1020 + 246 + 132) / 3 = 1398 / 3 ≈ 466
This solution is correct!
Solution 5:
1106, 220, 72
Verification:
(1106 + 220 + 72) / 3 = 1398 / 3 ≈ 466
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 1398 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.
