What three numbers have an average of 212?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 212. This means if we add these three numbers together and divide by 3, we should get 212.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 212 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 212 * 3 = x + y + z
- So, the sum of our three numbers should be: 636
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 636.
Solution 1:
212, 212, 212
Verification:
(212 + 212 + 212) / 3 = 636 / 3 ≈ 212
This solution is correct!
Solution 2:
212, 212, 212
Verification:
(212 + 212 + 212) / 3 = 636 / 3 ≈ 212
This solution is correct!
Solution 3:
522, 73, 41
Verification:
(522 + 73 + 41) / 3 = 636 / 3 ≈ 212
This solution is correct!
Solution 4:
609, 24, 3
Verification:
(609 + 24 + 3) / 3 = 636 / 3 ≈ 212
This solution is correct!
Solution 5:
382, 212, 42
Verification:
(382 + 212 + 42) / 3 = 636 / 3 ≈ 212
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 636 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.
