How to Convert a Fraction to a Decimal

Converting a fraction to a decimal is as simple as dividing the numerator (top number) by the denominator (bottom number). You can use long division or a calculator.

Terminating Decimals

A terminating decimal has an end. It doesn't go on forever. This happens when the denominator's only prime factors are 2 and 5 (after simplifying the fraction).

Example: 3/4 = 3 ÷ 4 = 0.75

Repeating Decimals

A repeating decimal has a digit or group of digits that repeats forever. This happens when the denominator has prime factors other than 2 or 5.

Example: 1/3 = 1 ÷ 3 = 0.33333...

Frequently Asked Questions

Common questions about converting fractions to decimals

01 How do you convert a fraction to a decimal?

You divide the numerator (the top number) by the denominator (the bottom number) using long division or a calculator.

02 What is the long division method?

Long division is a standard procedural method for dividing numbers. For fractions, you divide the top number by the bottom number, adding a decimal point and zeroes to the dividend as needed.

03 How do I know if a fraction will result in a terminating decimal?

A fraction in simplest form will result in a terminating decimal if the only prime factors of its denominator are 2 and 5.

04 When does a fraction result in a repeating decimal?

A fraction in simplest form will result in a repeating decimal if its denominator has any prime factors other than 2 or 5 (like 3, 7, 11).

05 Can the numerator be larger than the denominator?

Yes. This is called an improper fraction, and converting it to a decimal will result in a number greater than or equal to 1.
