How To Convert A Fraction To A Decimal In Python

Converting fractions to decimals is an important skill in mathematics. In Python, you can easily convert a fraction to a decimal using built-in functions. In this tutorial, we will learn how to convert a fraction to a decimal in Python.

Let’s say we have the fraction 3/4. We want to convert it to a decimal.

Steps:

  1. Import the fractions module using the following code:
1
import fractions
  1. Create a fraction using the fractions module:
1
my_fraction = fractions.Fraction(3, 4)
  1. Convert the fraction to a decimal using the float() function:
1
my_decimal = float(my_fraction)
  1. Print the decimal:
1
print(my_decimal)

The output will be 0.75.

Here’s the full code:

1
2
3
4
5
6
import fractions
 
my_fraction = fractions.Fraction(3, 4)
my_decimal = float(my_fraction)
 
print(my_decimal)

Note: The fractions module is included in Python by default, so you do not need to install any external libraries.

Conclusion

In this tutorial, we learned how to convert a fraction to decimal in Python. We used the fractions module to create a fraction and the float() function to convert it to a decimal. Python makes it simple to perform mathematical calculations like this, making it a versatile language for data science and other numerical applications.
