What three numbers have an average of 414?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 414. This means if we add these three numbers together and divide by 3, we should get 414.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 414 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 414 * 3 = x + y + z
- So, the sum of our three numbers should be: 1242
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1242.
Solution 1:
414, 414, 414
Verification:
(414 + 414 + 414) / 3 = 1242 / 3 ≈ 414
This solution is correct!
Solution 2:
414, 414, 414
Verification:
(414 + 414 + 414) / 3 = 1242 / 3 ≈ 414
This solution is correct!
Solution 3:
310, 852, 80
Verification:
(310 + 852 + 80) / 3 = 1242 / 3 ≈ 414
This solution is correct!
Solution 4:
84, 288, 870
Verification:
(84 + 288 + 870) / 3 = 1242 / 3 ≈ 414
This solution is correct!
Solution 5:
1029, 77, 136
Verification:
(1029 + 77 + 136) / 3 = 1242 / 3 ≈ 414
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 1242 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.
