This fraction calculator covers three common tasks in one place: reducing a fraction to lowest terms, performing addition, subtraction, multiplication, or division on two fractions, and comparing two fractions. Depending on the mode, it adds a simplified fraction, mixed-number view, decimal, percentage, or common-denominator comparison, making it useful for classwork, homework checks, and everyday arithmetic.
The input model is deliberately explicit: enter the numerator and denominator separately, and make both integers. The page does not parse mixed numbers or decimal numerators and denominators directly. If your source value is a decimal, use the decimal fraction converter instead.
18/24 to lowest terms.The page has three modes: simplify, operation, and compare. Simplify needs only the first fraction; the other two modes also need a second fraction. Choosing the mode first keeps the required fields clear.
Every numerator and denominator field must contain an integer, and denominators cannot be 0. Negative values are allowed. If the negative sign is placed in a denominator, the page moves it to the numerator so the displayed denominator stays positive. A zero fraction is normalized to 0/1.
It supports simplification, addition, subtraction, multiplication, division, and comparison of two fractions.
No. The current fields accept integer numerators and integer denominators only; convert a mixed number to an improper fraction first.
Yes. The page moves the negative sign to the numerator side before displaying and calculating the result.
The divisor fraction cannot equal zero, and neither denominator can be zero.
They are readable decimal displays rounded to at most 8 decimal places; use the simplified fraction when an exact form matters.
Use integer numerators and denominators to simplify, add, subtract, multiply, divide, or compare fractions with reduced and readable results.
