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:
1051, 105, 269
Verification:
(1051 + 105 + 269) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 4:
1362, 49, 14
Verification:
(1362 + 49 + 14) / 3 = 1425 / 3 ≈ 475
This solution is correct!
Solution 5:
408, 458, 559
Verification:
(408 + 458 + 559) / 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.
