Percents are a way of expressing a number as a fraction of 100. The percent symbol (%) is used to represent percents. For example, 50% is the same as the fraction 50/100, which reduces to 1/2.

To convert a percent to a decimal, divide the percent by 100. For example, to convert 25% to a decimal, you would divide 25 by 100 to get 0.25.

To convert a percent to a fraction, simply write the percent as a fraction with a denominator of 100 and then simplify if possible. For example, 75% is equivalent to 75/100, which simplifies to 3/4.

To convert a fraction to a percent, divide the numerator by the denominator and then multiply by 100. For example, to convert 3/5 to a percent, you would divide 3 by 5 to get 0.6, and then multiply by 100 to get 60%.

To calculate a percentage of a number, you can use the following formula:

Percentage = (Part / Whole) x 100

For example, if you want to find 20% of 80, you would use the formula:

Percentage = (20 / 80) x 100 = 0.25 x 100 = 25

Percentages are used in many real-life situations, such as calculating discounts, tips, taxes, and interest. Understanding how to work with percentages is important for managing personal finances and making informed decisions about purchases and investments.
