Reviewed by Calculator Editorial Team

Converting decimals to fractions is a fundamental math skill that's useful in many areas, from cooking measurements to financial calculations. This guide will show you how to convert 0.15 to a fraction, explain the process, and provide practical examples.

How to Convert 0.15 to a Fraction

Converting a decimal like 0.15 to a fraction involves understanding the place value of the decimal digits. Here's a simple method to do it:

Step 1: Write the decimal as a fraction with a denominator of 1 (0.15 = 15/100).

Step 2: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

Step 3: The simplified form is your final fraction.

For 0.15, the GCD of 15 and 100 is 5, so we divide both by 5 to get 3/20.

Step-by-Step Conversion

  1. Start with the decimal: 0.15
  2. Count the decimal places: 0.15 has two decimal places
  3. Write the decimal as a fraction with a denominator of 100 (since there are two decimal places): 15/100
  4. Find the greatest common divisor (GCD) of 15 and 100: 5
  5. Divide both numerator and denominator by 5: (15 ÷ 5)/(100 ÷ 5) = 3/20

Remember: The denominator should always be 10, 100, 1000, etc., based on the number of decimal places in your original decimal.

Simplifying the Fraction

After converting 0.15 to 15/100, we simplify it by dividing both the numerator and denominator by their GCD, which is 5 in this case. This gives us the simplest form of the fraction, 3/20.

Original Decimal Fraction Form Simplified Fraction
0.15 15/100 3/20
0.25 25/100 1/4
0.75 75/100 3/4

Worked Examples

Example 1: Converting 0.15 to a Fraction

Let's convert 0.15 to a fraction step by step:

  1. Write 0.15 as 15/100
  2. Find the GCD of 15 and 100: 5
  3. Divide both by 5: (15 ÷ 5)/(100 ÷ 5) = 3/20

The simplified fraction is 3/20.

Example 2: Converting 0.375 to a Fraction

Let's try another example to reinforce the process:

  1. Write 0.375 as 375/1000
  2. Find the GCD of 375 and 1000: 125
  3. Divide both by 125: (375 ÷ 125)/(1000 ÷ 125) = 3/8

The simplified fraction is 3/8.
