    Fraction Calculator With Steps

    Use this fraction calculator to add, subtract, multiply, divide, and simplify fractions in seconds. Enter proper fractions, improper fractions, mixed numbers, or whole numbers, then choose an operation to see the exact answer, decimal equivalent, and clear calculation steps.

    Whether you are checking homework, adjusting a recipe, working with measurements, or learning fraction rules, this tool helps you understand the answer instead of only displaying it.

    How to use the fraction calculator

    1. Enter the first whole number, numerator, and denominator.
    2. Choose addition, subtraction, multiplication, or division.
    3. Enter the second fraction.
    4. View the simplified answer, improper fraction, mixed-number form, and decimal value.
    5. Review the working steps or copy the result.

    You can leave the whole-number field as 0 when you only need to calculate a regular fraction such as 2/3.

    Add and subtract fractions

    To add or subtract fractions, both fractions need the same denominator. The calculator finds a common denominator, converts both fractions, then simplifies the final answer.

    For example:

    2/3 + 1/4

    The least common denominator is 12.

    2/3 = 8/12 1/4 = 3/12

    Then add the numerators:

    8/12 + 3/12 = 11/12

    Multiply fractions

    To multiply fractions, multiply the numerators together and multiply the denominators together.

    For example:

    3/5 × 2/7 = 6/35

    The answer is already simplified because 6 and 35 have no common factor other than 1.

    Divide fractions

    When dividing fractions, keep the first fraction, change division to multiplication, and flip the second fraction.

    For example:

    3/4 ÷ 2/5

    Flip 2/5 to become 5/2:

    3/4 × 5/2 = 15/8

    As a mixed number, 15/8 = 1 7/8.

    Simplifying fractions

    A fraction is simplified when its numerator and denominator have no common factors other than 1. The calculator uses the greatest common divisor to reduce answers to their lowest terms.

    For example:

    18/24

    Both 18 and 24 can be divided by 6:

    18 ÷ 6 = 3 24 ÷ 6 = 4

    So:

    18/24 = 3/4

    Mixed numbers and improper fractions

    A mixed number combines a whole number and a fraction, such as 2 1/3. An improper fraction has a numerator larger than its denominator, such as 7/3.

    The calculator automatically converts mixed numbers into improper fractions for calculation, then shows the final result in both forms where useful.

    For example:

    2 1/3 + 1 1/2 = 3 5/6

    Fraction calculator FAQs

    Can I use negative fractions?

    Yes. Enter a negative whole number or numerator to calculate values such as −1/2 + 1/4.

    Can a denominator be zero?

    No. Division by zero is undefined, so a fraction denominator must always be a non-zero number.

    Does the calculator simplify answers automatically?

    Yes. Every result is reduced to its lowest terms whenever possible.

    Why does the tool show a decimal answer too?

    Fractions give the exact value. The decimal is included as a helpful approximation and is clearly labelled as rounded.

    Is this calculator useful for recipes and measurements?

    Yes. It can help combine cooking quantities, construction measurements, craft dimensions, and other everyday fractional values.
