At its core, understanding percentages is crucial for daily financial dealings, academic assessments, and many real-world situations. A percentage is just another way of expressing a ratio or a fraction of 100, which is why "percent" essentially means "per hundred." Here's how you can calculate a percentage:
- To convert a percentage to a decimal, simply divide it by 100. For instance, 20% as a decimal is 0.20.
- To convert a decimal back to a percentage, multiply by 100 or shift the decimal point two places to the right.
Practical Uses of Percentages
- Discounts: Calculate the reduced price after a percentage discount is applied.
- Tipping: Determine the appropriate tip amount in restaurants or services.
- Sales Tax: Compute the tax amount on a purchase when tax rates are given as percentages.

Percentages are not just numbers; they have a wide range of applications:

- Subtract this amount from the original price to get the final price.
Tipping
Tipping is often based on percentages:
- For a 15% to 20% tip, multiply the bill total by 0.15 or 0.20 respectively.
Sales Tax
Sales tax is another common use:
- If your state has a 7% sales tax, multiply the purchase amount by 0.07 to find out the tax amount.

Once you've mastered the basic calculations, you can move on to more complex scenarios:
- Percentage Increase/Decrease: Calculate the change in value as a percentage of the original value.
- Multiple Percentages: Applying more than one percentage change to a single amount.
Multiple Percentages
For example, if you want to apply a 10% increase followed by a 20% discount:
- First, calculate the new amount after the increase.
- Then, apply the discount to the new increased amount.
<p class="pro-note">๐ง Note: When dealing with multiple percentages, ensure you understand the order of operations to avoid errors.</p>
