text: explain this !!!!? there are 100 paise is a rupee (rupee is india currency) so 1 rupee = 100 paise         = 10 x 10 paise         = 1/10 x 1/10 rupee         = 0.1 x 0.1 rupee         = 0.01 rupee         = 1 paise (as 0.01 rupee is nothing but 1 paise) what's wrong in this ? please explain. in (10 * 10) paise, one of the 10's refers to the number of paise while the other is the number of groups of 10 paise available. therefore when you convert to rupees, only one of the 10's should be converted.  => 1 rupee = 100 paise = 10 * 10paise =10 * 0.1 rupree =1 rupee
