Explanation:
In general, to convert a decimal number to a percentage, you multiply the decimal by 100. This is because a percentage is simply a way of expressing a fraction or ratio out of 100. The process of converting involves shifting the decimal point two places to the right, which is equivalent to multiplying by 100. This method can be applied universally for all decimal numbers.
For example:
- If you have 0.5, multiplying it by 100 gives 50%, which is the same as moving the decimal point two places to the right.
- If you have a larger number, such as 2.75, multiplying by 100 gives 275%.
Understanding this process is important because percentages are a common way of presenting data in everyday life, whether in business, education, or health. A percentage makes it easier to compare different quantities, as it normalizes the numbers to a common scale of 100.
For 0.0318, multiplying by 100 and expressing it as 3.18% allows you to understand it as a part of 100. When numbers are presented as percentages, they are often easier to understand and apply in real-world contexts, such as financial calculations, sales data, or statistical analysis.
