Frequently asked questions

How do I enter a mixed number?

Put a space between the whole number and the fraction, like 2 1/4 for two and a quarter. Negative numbers like -1 1/2 work too.

How do you add fractions with different denominators?

Find the LCM of the denominators, convert both fractions to that denominator, then add the numerators. The steps show exactly this.

How do you divide fractions?

Flip the second fraction (swap its top and bottom) and multiply. For example 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2.

Can I use decimals?

Yes. 0.5 is treated as 1/2 and 1.25 as 5/4, so you can mix decimals and fractions.

Is the answer always simplified?

Yes. The result is reduced to its lowest terms by dividing top and bottom by their HCF.
