Frequently Asked Questions
How do I add two fractions?
Give both fractions the same denominator, add the numerators, then reduce. For example, one half plus one third becomes three sixths plus two sixths, which is five sixths.
How do I multiply fractions?
Multiply the top numbers together and the bottom numbers together, then reduce. For example, one half times one third is one sixth.
How do I divide fractions?
Flip the second fraction and multiply. For example, one half divided by one third is one half times three over one, which is three halves or 1.5.
What is a mixed number?
A mixed number combines a whole number and a fraction, such as one and one half. The tool shows this form when the result is larger than one.
Does it reduce the fraction for me?
Yes. The answer is always reduced to its lowest terms by dividing the top and bottom by their greatest common divisor.
