        Decimal Notation of Money

        100 paise = 1 rupee

        If we divide both sides by 100,

        we get,  100   paise =   1   rupee or 1 paise = 0.01 rupee
                 100            100


        Similarly, 5 paise = 0.05 rupee, 10 paise = 0.10 rupee, 15 paise = 0.15 rupee, etc.

        Conversion of Rupees into Paise and Vice-Versa

            ™   To convert rupees into paise, we multiply the amount                    Fact-o-meter
               by 100.
            ™   To convert paise into rupees, we divide the amount                     �  ` 1 = 100 paise (p)
                                                                                                      1
               by 100.                                                                 �  1 paise = `  100
        Let’s learn through examples.                                                            = ` 0.01
