Answer 1

Answer:

1. 1,000,000 milligrams makes 1 kilogram.

2.4000mg or 0.004kg.

2. Given:

A box contains 200 medicine tablets each weighing 200mg.

To find:

Total weight of all the tablets in the box in mg and kg also.

Solution:

Since, Weight if 1 tablet = 20mg.

Therefore, Weight of 200 tablets = 200×20 mg.

=> 4000mg.

We know that, 1 kg = 1,000,000mg.

Therefore, 4000mg = 4000/1000000 kg.

=> 0.004kg.

Hence, In mg weight of all the tablets is 4000mg.

And, In kg weight of all the tablets is 0.004kg.
