# Vilma is prescribed 250mg tablet by her doctor. If she takes it two times a day for a week. Express the total consumption in grams.

Hint:

## The correct answer is: 3.5

### The given weight of the medicine is 250mg.The number of times she takes the medicine per day is 2.The number of days she take medicine is 7.Let’s find total number of medicines consumed by her.Total number of medicine = number of times per day × number of daysTotal number of medicine = 2 × 7= 14Now, let’s find the total weight.Total weight = total number of medicines × weight of one medicine= 14 × 250mg= 3500 mgBut we are asked to find weight in grams. So, we will have to convert the total weight in grams. To convert the weight into grams, we am b know the relation between mg and grams.1 mg = 0.001 gramsNow to convert 3500 mg into grams, we will multiply the quantity by 0.001.3500 mg = 3500 × 0.001 grams= 3.5 grams.Therefore, the total consumption of the medicine in grams is 3.5.

For such questions, we should know about the different units and relation between them.
