What is 10% of 40 – JavaTpoint?

To calculate 10% of 40, you simply multiply 40 by 0.10 (since 10% is equivalent to 0.10 in decimal form). Here’s how to do the calculation:

Calculation:

40×0.10=440 \times 0.10 = 4

So, 10% of 40 is 4.

If you want to perform this calculation programmatically in Java, here’s how you can do it:

Java Code Example:

public class PercentageCalculator {
    public static void main(String[] args) {
        double number = 40;
        double percentage = 10;
        
        double result = (percentage / 100) * number;
        
        System.out.println(percentage + "% of " + number + " is " + result);
    }
}

Output:

10% of 40 is 4.0

In the above Java code:

• We define the number (40) and the percentage (10).
• The formula (percentage / 100) * number calculates the percentage of the number.
• The result is printed to the console.

This is a basic example, but it can easily be adapted for other percentages or numbers.
