Answer: 30% of 100 is 30.
To find 30% of 100, you multiply 100 by the decimal equivalent of 30%. Since percentages are based on a scale of 100, 30% can be written as 30/100, which simplifies to 0.30.
The calculation is as follows:
100 × 0.30 = 30
This calculation is a basic yet essential aspect of understanding percentages, which are a fundamental part of everyday mathematics. Percentages are widely used in various contexts, such as calculating discounts, understanding statistics, and determining proportions in recipes, finance, and science. For example, if a store offers a 30% discount on an item priced at $100, the discount amount would be 30% of $100, which is $30. Thus, the sale price of the item would be $100 – $30 = $70. The ability to calculate percentages is not only crucial for academic purposes but also for practical, everyday decision-making.
