You can multiply any two rational numbers (fractions) and get a rational number. Similarly, you can multiply any two rational expressions and get a rational expression.

You can divide any two rational numbers and get a rational number with the exception of zero. Division is not defined for dividing by zero. Similarly, you can divide any two rational expressions and get a rational expression with the exception of an expression which is equivalent to zero.
