What three numbers have an average of 474?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 474. This means if we add these three numbers together and divide by 3, we should get 474.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 474 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 474 * 3 = x + y + z
- So, the sum of our three numbers should be: 1422
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1422.
Solution 1:
474, 474, 474
Verification:
(474 + 474 + 474) / 3 = 1422 / 3 ≈ 474
This solution is correct!
Solution 2:
474, 474, 474
Verification:
(474 + 474 + 474) / 3 = 1422 / 3 ≈ 474
This solution is correct!
Solution 3:
826, 436, 160
Verification:
(826 + 436 + 160) / 3 = 1422 / 3 ≈ 474
This solution is correct!
Solution 4:
1382, 12, 28
Verification:
(1382 + 12 + 28) / 3 = 1422 / 3 ≈ 474
This solution is correct!
Solution 5:
308, 483, 631
Verification:
(308 + 483 + 631) / 3 = 1422 / 3 ≈ 474
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 1422 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.
