#' ## Rational numbers in Julia
#' Rational number in julia can be constructed with the `//` operator:

x = 1//3
y = 2//5

#' Operations with rational number returns a new rational number

x + y

#-

x * y

#' Everytime a rational number is constructed, it will be simplified
#' using the `gcd` function, for example `2//4` simplifies to `1//2`:

2//4

#' and `2//4 + 2//4` simplifies to `1//1`:

2//4 + 2//4
