Fraction Calculator with Steps
Add, subtract, multiply, and divide fractions with simplification and step-by-step work.
Follow the same sequence you would use on paper. Mixed numbers are converted to improper fractions first, then each operation is shown one step at a time.
LOCAL TOOL: Fraction math and the walkthrough are generated entirely in your browser.
Whole numbers, fractions, and mixed numbers all belong in the same calculator.
If a mixed number is entered, the walkthrough first shows how to turn it into an improper fraction. Addition and subtraction then find the least common denominator, multiplication works straight across, and division uses keep-change-flip. Every result is simplified and checked as a mixed number and decimal when appropriate.
How to use the fraction calculator
Enter the numerator above the fraction bar and denominator below it. Use the optional Whole box when you have a mixed number such as 2 3/4. Choose add, subtract, multiply, or divide, then select Solve + Walk Me Through It. The calculator simplifies the answer and shows the fraction work in the same order you would use on paper.
Fraction calculator examples
1/2 + 3/4 = 1 1/4. Addition first rewrites 1/2 as 2/4, then adds 2/4 + 3/4 = 5/4 before converting the improper fraction to a mixed number.
5/6 − 1/3 = 1/2. Rewrite 1/3 as 2/6, subtract to get 3/6, then simplify by dividing the numerator and denominator by 3.
2/3 × 4/5 = 8/15. Multiply the numerators and denominators, then reduce if a common factor exists.
3/4 ÷ 2/5 = 15/8 = 1 7/8. Keep the first fraction, change division to multiplication, flip the second fraction, and simplify the result.
Common fraction questions
How do you add fractions with different denominators? Find a common denominator, rewrite both fractions with that denominator, add the numerators, and simplify.
Does this calculator handle mixed numbers? Yes. It converts mixed numbers to improper fractions for the calculation and converts the final result back to a mixed number when useful.
Are answers simplified automatically? Yes. Results are reduced to lowest terms. For focused practice, try the fraction worksheet generator, or use the fraction simplifier when you only need to reduce one fraction.
