What three numbers have an average of 424?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 424. This means if we add these three numbers together and divide by 3, we should get 424.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 424 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 424 * 3 = x + y + z
- So, the sum of our three numbers should be: 1272
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1272.
Solution 1:
424, 424, 424
Verification:
(424 + 424 + 424) / 3 = 1272 / 3 ≈ 424
This solution is correct!
Solution 2:
424, 424, 424
Verification:
(424 + 424 + 424) / 3 = 1272 / 3 ≈ 424
This solution is correct!
Solution 3:
35, 1131, 106
Verification:
(35 + 1131 + 106) / 3 = 1272 / 3 ≈ 424
This solution is correct!
Solution 4:
571, 263, 438
Verification:
(571 + 263 + 438) / 3 = 1272 / 3 ≈ 424
This solution is correct!
Solution 5:
1150, 112, 10
Verification:
(1150 + 112 + 10) / 3 = 1272 / 3 ≈ 424
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 1272 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.
