With Johto Mono, you can add a touch of retro to your text with the fraction. In mathematics, a fraction (from Latin fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. The fraction is a small, diagonal shape that is placed over a letter.
