Mathematical Foundations of "What is 30 of 10"

Understanding the mathematical foundation of "what is 30 of 10" involves delving into the basic principles of percentage calculations. A percentage is a way of expressing a number as a fraction of 100, and it is denoted using the percent symbol (%). When we say "30 of 10," it implies finding 30% of the number 10. This calculation is fundamental in mathematics and can be represented by the formula:

1. Convert the percentage into a decimal by dividing by 100. For 30%, it becomes 0.30.
2. Multiply the decimal by the number in question, which in this case is 10: 0.30 x 10.

Thus, 30% of 10 equals 3. This simple calculation serves as the basis for understanding more complex percentage-related problems and is widely applicable in various fields.

How to Calculate 30% of 10?

Calculating 30% of 10 is a straightforward process that involves a few basic steps. Here's a step-by-step guide to performing this calculation accurately:

• Step 1: Convert the percentage (30%) into a decimal. To do this, divide 30 by 100, resulting in 0.30.
• Step 2: Multiply the decimal by the given number (10). Therefore, 0.30 multiplied by 10 equals 3.

By following these steps, you can easily determine that 30% of 10 is 3. This method can be applied to calculate any percentage of a given number, making it a valuable skill for everyday calculations.

Real-World Applications of Percentage Calculations
