Fraction Calculator

The #1 online fraction calculator. Easily add, subtract, multiply, divide and simplify fractions. Because math with fractions can be difficult, we developed the fraction calculator. Fill in your two fractions below (the numerator above the line and the denominator below the line) and submit if you want to add, subtract, multiply or divide. The fraction calculator shows you step-by-step how to add, subtract, multiply or divide your fractions and automatically reduces the result to the lowest terms. With the help of this calculator you can solve all your fraction problems.

Work and steps of the calculation

The fraction calculator has not yet performed a calculation. Enter two fractions above (the numerators above the lines and the denominators below the lines) and choose your action (adding, subtracting, multiplying or dividing). Depending on whether you want to add, subtract, divide, or multiply fractions, you need to follow different rules and steps. The fraction calculator not only gives you the result, but also shows you the rules and steps that apply to your calculation. In addition, the result is automatically simplified (reduced) using the greatest common factor. If the result is an fraction in which the numerator is greater than or equal to the denominator (improper fraction), the fraction calculator will convert it to a mixed fraction. All steps of the calculation, including simplifying and converting to a mixed number (if necessary), are shown here.

What is a fraction?

A fraction is the result of a division of two whole numbers or in other words a mathematical representation of a number that expresses a part of a whole. It consists of two numbers separated by a horizontal or diagonal line (fraction bar), with one number above the line and one below. The number above the fraction bar is called the numerator, and the number below the fraction bar is called the denominator.

The numerator represents the number of equal parts or portions you have, and the denominator represents the total number of equal parts into which the whole is divided. Fractions are used to describe quantities that are not whole numbers and can represent values that are smaller or larger than one. The denominator can not be zero. If the numerator is smaller than the denominator, the fraction is located between 0 and 1.

Reduce fractions

Each fraction can be reduced to it’s simplest form, in which the numerator and denominator are as small as possible. Try this reduce fraction calculator to simplify your fraction and find the Greatest Common Factor (GCF).
