Frequently Asked Questions

How does fraction addition work?

To add fractions, find a common denominator by multiplying both denominators. Then add the numerators. The result is automatically simplified to its lowest terms.

What is a mixed number?

A mixed number combines a whole number and a proper fraction, e.g. 1 and 1/2. The calculator shows the mixed number form when the result is an improper fraction.

How do I divide fractions?

To divide fractions, multiply by the reciprocal of the second fraction. For example, 1/2 ÷ 1/3 = 1/2 × 3/1 = 3/2.

Are the results automatically simplified?

Yes. All results are automatically reduced to their simplest form using the GCD (Greatest Common Divisor) algorithm.

Does this run in my browser?

Yes. All calculations are done locally in JavaScript. Nothing is sent to any server.

How does fraction division work?

Dividing by a fraction is the same as multiplying by its reciprocal. For example, 1/2 / 1/3 = 1/2 x 3/1 = 3/2.

What is an improper fraction?

An improper fraction has a numerator larger than its denominator (e.g. 5/3). It can also be written as a mixed number: 1 and 2/3.

Are results always fully simplified?

Yes. All results are divided by the GCD of the numerator and denominator to produce the simplest form.
