Percent, Fractions, and Decimals can represent the same value in different formats. For example, the benchmark value of 50% is the same as ½ and 0.50. To make algebra calculations and real life calculations easier, learn to convert between percents, fractions, and decimals.

To convert a decimal to a percent: multiply by 100 or move the decimal point two spaces to the right then add the percent sign. To convert a decimal to a fraction, use place value to help you determine the denominator, and remember to reduce to lowest terms.

To convert a fraction to a decimal, use long division to divide the numerator by the denominator, and to convert that number to a fraction, multiply the quotient by 100 then add the percent sign. It’s easy to convert a percent to a fraction. Remember percent means per cent or per hundred, so place the number value of the percent over 100 then reduce the resulting fraction to lowest terms.

Understanding the relationship of percents, fractions, and decimals and how to calculate equations including percents, fractions, and decimals is very important in the real world, especially for making good consumer decisions.
