Number Fraction Calculator
Add, subtract, multiply and divide fractions and mixed numbers — with every step of the working shown, free. Solvers charge for the steps; here they are just part of the answer.
Step-by-step working
How it works
Mixed numbers are first converted to improper fractions (whole × denominator + numerator). Adding and subtracting need a common denominator — the least common multiple of both denominators — while multiplying goes straight across, and dividing flips the second fraction and multiplies (keep, change, flip). Finally the result is simplified by dividing top and bottom by their greatest common divisor, and converted back to a mixed number, a decimal and a percent. Every one of those steps is listed under the result.
Frequently asked questions
How do I add fractions with different denominators?
Find a common denominator — the least common multiple of the two denominators — rewrite both fractions with it, then add the numerators. 1/2 + 1/3 becomes 3/6 + 2/6 = 5/6. The steps above show this for your numbers.
Why do you flip the second fraction when dividing?
Dividing by a fraction asks "how many of these fit into that?" — which is the same as multiplying by its reciprocal. So 3/4 ÷ 2/5 = 3/4 × 5/2 = 15/8.
How do I enter a mixed number like 2¾?
Put 2 in the whole part, 3 in the numerator and 4 in the denominator. It is converted to 11/4 behind the scenes and the result is converted back to a mixed number for you.
Is the step-by-step working really free?
Yes. Photo-and-solver apps typically charge a subscription to reveal steps; here the full working is shown for every calculation at no cost.
