Answer 2

Answer:

Step-by-step explanation: 1km = 1000m

                                               1m= 100cm

IN KM: 1 cm = 1/100*1000 Km

           = 1/100000

         20cm= 20/10000km

          = 2/1000

         = 1/500

          = 0.005

In M: 1cm= 1/100m

        20cm= 20/100m

        = 2/10

         = 0.5
