Round #629

What is 12 percent of 350?

To find 12 percent of 350, you can use the following formula: \[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \] In this case, we want to find what part is 12 percent of 350. So, we rearrange the formula to solve for the part: \[ \text{Part} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Whole} \] Substituting the given values: \[ \text{Part} = \left( \frac{12}{100} \right) \times 350 \] Now, calculate it: \[ \text{Part} = 0.12 \times 350 = 42 \] So, 12 percent of 350 is **42**.

To calculate 12 percent of 350, you can use simple arithmetic in C#. Here's how you can do it: ```csharp using System; class Program { static void Main() { double number = 350; double percentage = 12; // Calculate the result double result = (percentage / 100) * number; Console.WriteLine($"{percentage}% of {number} is {result}"); } } ``` ### Explanation: 1. **Variables**: We define two variables, `number` and `percentage`, to hold the values 350 and 12 respectively. 2. **Calculation**: To find 12 percent of 350, we first convert the percentage to a decimal by dividing it by 100 (`percentage / 100`). Then, we multiply this decimal by the number (`(percentage / 100) * number`). 3. **Output**: Finally, we print the result using `Console.WriteLine`. This code is straightforward and follows C# best practices for performing arithmetic operations and outputting results.
