# fraction

### /ˈfrækʃən/

Other forms: fractions; fractioning; fractioned

A fraction is a part of a whole. If two of you split the take from a bank heist, you would each get half. If you had a getaway driver, then the money would be split three ways, into fractions of one-third each.

The quotient of two numbers is called a fraction, as is the action of performing division. Most of us, however, think of a fraction as a small part of an item — as in: "You only use a fraction of your actual brain power in the course of your life." Just think of a whole as a pie, and a fraction as a slice of that pie.
