Method II in this method denominators of the given rational numbers are made equal by using the following steps :

Method III in the method to test the equality of two rational numbers (a)/(b) and (c)/(d) we use the following result: :(a)/(b)=(c)/(d)hArr a xx d=b xx c

An alternative method to find rational numbers between two rational numbers

Green method of bleaching of paper can be made using the following chemical

method I in order to test equality of the rational numbers we express both the rational numbers in the standard form.if they have the same standard form they are equal otherwise they are not equal
