Frequently Asked Questions

How do you add or subtract fractions with different denominators?

To add or subtract fractions with unlike denominators, find the Least Common Denominator (LCD), convert each fraction to an equivalent fraction with that denominator, add or subtract numerators, and reduce to lowest terms.

How do you multiply and divide fractions?

To multiply fractions, multiply numerators together and denominators together. To divide fractions, invert the second fraction (find its reciprocal) and multiply it by the first fraction.

What is the difference between a mixed number and an improper fraction?

An improper fraction has a numerator greater than or equal to its denominator (e.g. 7/4). A mixed number expresses the same value as a whole number and proper fraction combined (e.g. 1 3/4).

Can this calculator handle negative fractions?

Yes. You can input negative values in numerators or whole numbers to solve signed fractional algebraic equations accurately.

Is this Fraction Calculator free for classroom use?

Yes, completely free with no usage limits, no trial periods, and no registration required for educational and personal use.
