How do you represent fractions in computers?

Answer 1

Some commonly used fractions have special characters, for example "1/2" or "1/3". In Windows, these can be found with the Charmap application; or, in Microsoft Word, give the command to insert a symbol.

For fractions in general, you can write them horizontally, separated with a slash, for example 2/5. Or, to make them look neater, you can use an equation editor; for example, there is one included with Microsoft Office, at least in some versions.
