Formula

Converting between decimals and percentages is straightforward once you understand the basics. Let’s break it down:

To convert a decimal to a percentage, multiply the decimal by 100 and add the percent sign (%).

Percentage=Decimal×100

Conversely, to convert a percentage to a decimal, divide the percentage by 100.

Decimal=Percentage100

Think of this conversion like moving a decimal point. For example, 0.75 becomes 75% by moving the decimal point two places to the right. Similarly, 75% becomes 0.75 by moving the decimal point two places to the left.

Example

Let’s say you’re looking at a store discount. The tag says you get a 25% discount, but you want to know what that is as a decimal to apply to the original price.

Using the formula:

Decimal=25100=0.25

So, a 25% discount is equivalent to 0.25 in decimal form.

Now, let’s say you see a price that’s $45.99, and you know the sales tax is 0.07 (or 7%). To find out the tax amount in dollars:

Tax=45.99×0.07=3.22

So, you’ll pay $3.22 in sales tax.
