What three numbers have an average of 475?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 475. This means if we add these three numbers together and divide by 3, we should get 475.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 475 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 475 * 3 = x + y + z
- So, the sum of our three numbers should be: 1425
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1425.
Solution 1:
475, 475, 475
Verification:
(475 + 475 + 475) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 2:
475, 475, 475
Verification:
(475 + 475 + 475) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 3:
878, 59, 488
Verification:
(878 + 59 + 488) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 4:
789, 213, 423
Verification:
(789 + 213 + 423) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 5:
809, 596, 20
Verification:
(809 + 596 + 20) / 3 = 1425 / 3 ≈ 475
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 1425 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.
