# Integers, Decimals, and Fractions

Integers are whole numbers that are represented by tick marks on a number line. In between these marks, there are large spaces that are described as decimals and fractions. A fraction is a way to divide a section between integers into equally-spaced segments. A decimal representation divides the space between 0 and 1 into ten different segments.
