What three numbers have an average of 412?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 412. This means if we add these three numbers together and divide by 3, we should get 412.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 412 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 412 * 3 = x + y + z
- So, the sum of our three numbers should be: 1236
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1236.
Solution 1:
412, 412, 412
Verification:
(412 + 412 + 412) / 3 = 1236 / 3 ≈ 412
This solution is correct!
Solution 2:
412, 412, 412
Verification:
(412 + 412 + 412) / 3 = 1236 / 3 ≈ 412
This solution is correct!
Solution 3:
1125, 85, 26
Verification:
(1125 + 85 + 26) / 3 = 1236 / 3 ≈ 412
This solution is correct!
Solution 4:
229, 591, 416
Verification:
(229 + 591 + 416) / 3 = 1236 / 3 ≈ 412
This solution is correct!
Solution 5:
191, 912, 133
Verification:
(191 + 912 + 133) / 3 = 1236 / 3 ≈ 412
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 1236 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.
