Fraction Calculator

Add, subtract, multiply and divide fractions with step-by-step solutions.

What is Fraction Calculator?

A fraction calculator performs arithmetic operations — addition, subtraction, multiplication, and division — on fractions and mixed numbers, automatically simplifying results to their lowest terms. Working with fractions by hand requires finding common denominators, cross-multiplying, and reducing results, all steps where errors are easy to make. This tool handles every step automatically.

Our fraction calculator accepts both proper fractions (like 3/4) and mixed numbers (like 2 1/3). It displays intermediate steps, showing how the common denominator was found and how the result was simplified, making it an excellent learning tool for students as well as a quick answer tool for professionals.

Fractions appear everywhere from cooking recipes and construction measurements to probability calculations and algebra. Students at every level from elementary school through university use fraction calculators to check their homework. Home cooks scaling recipes, carpenters measuring lumber, and engineers working with ratios all benefit from a fast, accurate fraction tool.

How to Use Fraction Calculator

  1. 1Step 1: Enter the numerator and denominator for your first fraction in the provided fields. If working with a mixed number, also enter the whole number part separately.
  2. 2Step 2: Select the operation you want to perform — addition (+), subtraction (−), multiplication (×), or division (÷) — using the operation selector between the two fraction inputs.
  3. 3Step 3: Enter the second fraction's numerator and denominator, again including a whole number if it is a mixed number. Double-check that values are correct before calculating.
  4. 4Step 4: Click Calculate to get the result. The tool displays the answer as both a simplified fraction and a decimal equivalent for maximum flexibility.
  5. 5Step 5: Review the step-by-step solution shown below the result to understand how the answer was reached, which is especially useful for students checking homework.

Benefits of Using Fraction Calculator

  • Automatic Simplification: Every result is automatically reduced to lowest terms, saving the extra step of manually finding the greatest common divisor and dividing through.
  • Mixed Number Support: Handles mixed numbers natively alongside proper and improper fractions, covering the full range of fraction formats encountered in real-world problems.
  • Step-by-Step Workings: Displays the intermediate steps of each calculation so students can follow the logic, compare with their own work, and identify where they went wrong.
  • Decimal Equivalent Display: Shows the decimal value of the result alongside the fraction, making it easy to compare with calculator outputs or use in further computations.
  • Covers All Four Operations: Addition, subtraction, multiplication, and division are all supported, making this a single tool for every type of fraction arithmetic problem.
  • No Signup Required: Works instantly in the browser with zero registration, making it ideal for quick homework help or on-the-spot calculations in the kitchen or workshop.

Example

A high school student is solving a word problem that requires adding 2 3/8 cups of flour to 1 5/6 cups. She opens the fraction calculator, enters 2 as the whole number and 3/8 as the fraction for the first value, selects addition, then enters 1 and 5/6 for the second value. The calculator instantly shows the result: 4 5/24 cups, along with the step showing that 3/8 was converted to 9/24 and 5/6 to 20/24 before adding. She can see the exact answer and also the decimal approximation of 4.208 cups. The step-by-step breakdown helps her understand how to find the least common denominator herself next time.
