What is a Fraction Calculator?

A Fraction Calculator is a specialized tool designed to perform mathematical operations on numbers that are not whole. Fractions represent a part of a whole, consisting of a numerator (the top number) and a denominator (the bottom number).

Our calculator simplifies the often-confusing process of finding common denominators and reducing fractions to their simplest form.

How to Use the Fraction Calculator

Performing fraction math is easy with our tool:

• Select Operation: Choose between Addition (+), Subtraction (-), Multiplication (×), or Division (÷).
• Enter Fractions: Input the numerator and denominator for both the first and second fractions.
• Get Results: The calculator will instantly provide the result in fraction form, its simplified version, and its decimal equivalent.

Fraction Math Rules

Here is a quick refresher on how fractions are calculated manually:

• Addition/Subtraction: You must first find a Least Common Denominator (LCD) so that both fractions have the same bottom number. Then, you add or subtract the numerators.
• Multiplication: Simply multiply the numerators together and the denominators together. No common denominator is needed.
• Division: Flip the second fraction (find its reciprocal) and then multiply it by the first fraction.

Fraction Calculator FAQs

What is a "simplified" fraction?

A fraction is simplified (or in "lowest terms") when the numerator and denominator have no common factors other than 1. For example, 2/4 is simplified to 1/2. Our calculator does this automatically for every result.

How do I convert a fraction to a decimal?

To convert a fraction to a decimal, simply divide the numerator by the denominator. For example, 3/4 becomes 0.75 (3 ÷ 4 = 0.75).

Can I use negative fractions?

Yes! Our calculator supports negative numbers in both the numerator and denominator. It will correctly apply the rules of signs (e.g., a negative divided by a negative is a positive).
