Add, subtract, multiply, and divide fractions or mixed numbers with step-by-step solutions. Simplify fractional results to their lowest terms instantly and convert fractions to decimals.
Fractions can often be difficult to calculate manually, especially when adding or subtracting fractions with unlike denominators. Our free online Fraction Calculator simplifies this process by allowing you to add, subtract, multiply, and divide fractions, mixed numbers, and whole numbers instantly, providing clear step-by-step solutions.
When adding or subtracting fractions, the calculator finds the Least Common Denominator (LCD) to convert the fractions before performing the operation. For multiplication, it multiplies the numerators and denominators directly, and for division, it multiplies by the reciprocal of the divisor. All final results are simplified to their lowest terms.
To add fractions with different denominators, first find the Least Common Denominator (LCD) to convert the fractions so they have the same denominator, add the numerators, and keep the denominator the same. Simplify the final fraction if possible.
To divide two fractions, multiply the first fraction by the reciprocal (flipped version) of the second fraction. For example, 1/2 divided by 3/4 becomes 1/2 * 4/3 = 4/6, which simplifies to 2/3.
A mixed fraction (or mixed number) is a combination of a whole number and a proper fraction, such as 2 1/3. It can be converted to an improper fraction by multiplying the whole number by the denominator and adding the numerator.
To simplify a fraction to its lowest terms, divide both the numerator (top) and denominator (bottom) by their Greatest Common Divisor (GCD). For example, 8/12 simplifies to 2/3 by dividing both numbers by 4.
