Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Percentages

A percentage is a way of expressing a number as a fraction of 100. It is often used to compare relative sizes or to represent proportions. For example, 7% means 7 out of every 100 parts, which can be useful in various applications such as finance, statistics, and everyday calculations.

Decimal Representation

Decimals are a way of representing fractions in a base-10 system. To convert a percentage to a decimal, you divide the percentage by 100. For instance, 7% as a decimal is calculated as 7 ÷ 100, which equals 0.07. This conversion is essential for performing calculations that involve percentages.

Conversion Process

The conversion process from percentage to decimal is straightforward and involves a simple mathematical operation. This process is crucial in various fields, such as finance, where calculations often require the use of decimals instead of percentages. Understanding this conversion allows for accurate computations in real-world scenarios.
