Answer 1

the weight of the 1 medicine tablet =20gm
the weight of the 200000 medicine tablet=200000*20mg=4000000mg...........(1)
se how I did
Suppose you have weight of 1 toffee = 2gm
then weight of 2 toffee= 2*weight of 1 toffee
= 2*2gm
=4gm
the total weight of all tablets in the box ( in gm= 4000000 mg from( 1)
=4000000*0.001 gm as (1mg=0.001gm)
=4000gm.........(2)
the total weight of all the tablets in the box (in kg) = 4000gm
=4000*0.001kg as (1gm=0.001kg)
=4kg
