{{ printedBook.courseTrack.name }} {{ printedBook.name }} The set of rational numbers, represented by the symbol $Q,$ is formed by all numbers that can be expressed as the ratio between two integers, $ba ,$ where $b =0.$ $-3,31 ,5,4531 $ All four of these examples are rational numbers. Note that integers are also rational, because they can always be written as fractions with a denominator of $1.$ $-3=1-3 ,5=15 $ Real numbers which are not rational are called irrational numbers.
