Question

A box of medicine contains 3,00,000 tablets each weighing 15mg. What is the total weight of all the tablets in the box in grams and in kilograms?

Answer 1

Weight of a tablet = 15 mg 

Weight of 3,00,000 tablets = 300000 × 15 

Weight of one box of tablets = 45,00,000 mg we know 1000 mg = 1 gram 

To convert mg into grams we have to divide grams by 1000 mg = 45,00,000 ÷ 1000 

Weight of one box of tablets in grams = 4500 grams. 

We know 1000g = 1kg

To convert ‘g’ into kilograms we have to divide kilograms by 1000g = \(\frac{4500}{1000}\) = 4.5 kg
