1/2 + 1/35/6
Enter simple fractions, mixed numbers, or improper fractions, choose an operation, and see the simplified answer with steps, decimal value, and a copy-ready result.
Add or subtract fractions with unlike denominators and see the common-denominator step.
Multiply fractions directly or divide by using the reciprocal of the second fraction.
Turn an improper fraction into a mixed number for homework, recipes, or measurements.
Compare the mixed-number, improper-fraction, and decimal forms before trusting the answer.

Quick answers about simplifying, mixed numbers, denominators, division, and privacy.
Use it to add, subtract, multiply, divide, simplify, and compare fractions. It works with simple fractions, improper fractions, mixed numbers, and negative values.
Put the whole number in the Whole box and the fraction part in the numerator and denominator boxes. For 2 1/4, enter Whole 2, Numerator 1, Denominator 4.
The main inputs are the numbers, operation, mode, or known values the calculator needs. Keep units consistent, enter percentages the way the page label shows, and use the examples as a quick check before trusting the answer.
Read the headline answer, then check the supporting lines and examples to understand how the calculator got there. If one input changes, rerun the tool and compare the new answer instead of guessing.
Check units, signs, rounding, and the selected mode before copying the answer. If the number feels weird, rerun one of the examples first, then put your own values back in slowly.
Fractions can only be added or subtracted directly when the parts are the same size. The calculator finds matching denominator pieces first, then combines the numerators.
Yes. The result is reduced to lowest terms, and the page also shows an improper fraction, a mixed-number form, and a decimal value.
Dividing by a fraction uses the reciprocal of the second fraction. The calculator flips the second fraction, multiplies, and then simplifies the answer.
The decimal is the same value written another way. It is useful when a recipe, measurement, or spreadsheet needs a decimal instead of a fraction.
No. A denominator cannot be zero, and the calculator will show an error if you try to calculate with one.
Use the LCM Calculator when you only need a common denominator. Use the GCF Calculator when you only need the largest shared factor for simplifying.
