What three numbers have an average of 465?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 465. This means if we add these three numbers together and divide by 3, we should get 465.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 465 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 465 * 3 = x + y + z
- So, the sum of our three numbers should be: 1395
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1395.
Solution 1:
465, 465, 465
Verification:
(465 + 465 + 465) / 3 = 1395 / 3 ≈ 465
This solution is correct!
Solution 2:
465, 465, 465
Verification:
(465 + 465 + 465) / 3 = 1395 / 3 ≈ 465
This solution is correct!
Solution 3:
896, 491, 8
Verification:
(896 + 491 + 8) / 3 = 1395 / 3 ≈ 465
This solution is correct!
Solution 4:
1116, 64, 215
Verification:
(1116 + 64 + 215) / 3 = 1395 / 3 ≈ 465
This solution is correct!
Solution 5:
348, 331, 716
Verification:
(348 + 331 + 716) / 3 = 1395 / 3 ≈ 465
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 1395 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.
