What three numbers have an average of 460?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 460. This means if we add these three numbers together and divide by 3, we should get 460.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 460 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 460 * 3 = x + y + z
- So, the sum of our three numbers should be: 1380
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1380.
Solution 1:
460, 460, 460
Verification:
(460 + 460 + 460) / 3 = 1380 / 3 ≈ 460
This solution is correct!
Solution 2:
460, 460, 460
Verification:
(460 + 460 + 460) / 3 = 1380 / 3 ≈ 460
This solution is correct!
Solution 3:
1289, 65, 26
Verification:
(1289 + 65 + 26) / 3 = 1380 / 3 ≈ 460
This solution is correct!
Solution 4:
71, 1233, 76
Verification:
(71 + 1233 + 76) / 3 = 1380 / 3 ≈ 460
This solution is correct!
Solution 5:
427, 498, 455
Verification:
(427 + 498 + 455) / 3 = 1380 / 3 ≈ 460
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 1380 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.
