# Word Problems of Converting Percent, Fractions, and Decimals

In this step-by-step guide, you will learn how to solve Word Problems related to Converting Between Percent, Fractions, and Decimals.

## A step-by-step guide

To convert a percent to a fraction, divide the percent by 100 and add the percent sign (%). For example, 25% can be written as 25/100 or 1/4.

To convert a fraction to a percent, divide the numerator by the denominator and multiply by 100. For example, 1/4 can be written as 25%.

To convert a decimal to a percent, multiply the decimal by 100 and add the percent sign (%). For example, 0.25 can be written as 25%.

To convert a percent to a decimal, divide the percent by 100. For example, 25% can be written as 0.25.

To convert a decimal to a fraction, you can use the following steps:

- Write the decimal as a fraction with a denominator of 1 followed by as many zeroes as the decimal has digits. For example, 0.25 would be written as 25/100.
- Simplify the fraction by dividing both the numerator and denominator by their greatest common factor (GCF).

To convert a fraction to a decimal, divide the numerator by the denominator. For example, 1/4 can be written as 0.25

**Word Problems of Converting Between Percent, Fractions, and Decimals – Examples 1**

Bettie is helping her mother clean out the basement. She finds a bolt that is 3/5 of a foot in diameter.

Write \(\frac{3}{5}\) of a foot as a decimal and percent.**Solution:**Divide 3 by 5 to write as a decimal. \(3÷5=0.6\)

Multiply \(\frac{3}{5}\) by 100 to write it as a percent. \(\frac{3}{5}×100=\frac{3}{5}×\frac{100}{1}=\frac{300}{5}=60\)

So, \(\frac{3}{5}\) is equal to 0.6 and \(60%\)

**Word Problems of Converting Between Percent, Fractions, and Decimals – Examples 2**

Carol is painting his bedroom. He uses 45% of a gallon.

Write 45% of a gallon as a fraction.**Solution:**45% is 45 parts out of 100. So, as a fraction, it is \(\frac{45}{100}\). Simplify \(\frac{45}{100}=\frac{45÷5}{100÷5}=\frac{9}{20}\).

To write 45% as a decimal, divide 45 by 100. \(45÷100=0.45\).
