Step-by-step explanation:

Weight of one tablet

=20milligram=20/1000 gram

Hope u understood

This is like;

Cost of 1 pen=5 ruppees

Cost of 5 pens=25 ruppees

Answer 2

Total number of medicine tablets = 2,00,000

weight of one tablet = 20 Milligram

so, weight of 2,00,000 tablets =

20 × 200000

= 40,00,000 Milligrams

since, 1kilogram = 1000 grams

and 1gram = 1000 milligrams

so, 1kilogram = 1000 × 1000

= 10,00,000

so, weight of 2,00,000 tablets in kilograms =

40,00,000 milligrams/ 10,00,000

= 4 kilogram

hope it will help you

good luck
