Explanation:

Dividing by a fraction is equivalent to multiplying by its reciprocal. The reciprocal of a fraction is obtained by reversing its numerator and denominator.

For example if we have do divide #a/b# by #c/d# i.e we are computing #a/b-:c/d#,

what we can do is multiply #a/b# by reciprocal of #c/d# i.e. by #d/c#

Hence #a/b-:c/dhArra/bxxd/c=(axxd)/(bxxc)# or #(ad)/(bc)#
