To add or subtract fractions, find a common denominator, adjust numerators accordingly, then combine. Multiply by multiplying numerators and denominators. Divide by multiplying by the reciprocal.
a/b ± c/d = (ad ± bc) / bd
Find the LCD (Least Common Denominator) for adding/subtracting
Multiply straight across: (a/b) × (c/d) = ac/bd
Divide by flipping the second fraction and multiplying
Always simplify your final answer by finding the GCD
Convert mixed numbers to improper fractions first
To convert to decimal, divide numerator by denominator
Calculate fractions with ease using our free online fraction calculator. Add, subtract, multiply, divide fractions, simplify, and convert between fractions, decimals, and percentages with step-by-step solutions.
To add or subtract fractions, find the Least Common Denominator (LCD), convert fractions to equivalent fractions with the LCD, then add or subtract numerators. Our calculator handles this automatically and shows each step.
Multiply fractions by multiplying numerators together and denominators together. Divide by flipping the second fraction and multiplying. Remember: Keep, Change, Flip for division.
Simplify fractions by finding the Greatest Common Divisor (GCD) of numerator and denominator, then dividing both by it. A fraction is fully simplified when GCD equals 1.
Convert fractions to decimals by dividing. Convert decimals to fractions by placing over powers of 10. Convert to percentages by multiplying by 100. Our converter handles all these transformations.
Mixed numbers combine whole numbers with fractions (2 1/2). Improper fractions have numerators larger than denominators (5/2). Convert between them easily with our calculator.
Every calculation shows detailed steps so you can learn the process. Perfect for students learning fraction arithmetic or anyone who wants to understand the math behind the answer.
