If a patient took one pill (0.250 g each) of an antibiotic every 6 hours for two weeks, how many total milligrams of antibiotic did he take for to week?

14000 mg he did take for the two weeks

Explanation:

Try to reason this problem:

1 day has 24 hours

If our patient takes the pill every 6 hour, he will take 4 pills per day

1 week has 7 days

So, in 2 weeks we have 14 days.

As 4 pills are taken each day, at the end of the 2 weeks he would have taken 56 pills.

Let's make a rule of three:

1 pill weighs 0.250 g

Then 56 pills weigh (56. 0.250) = 14 g

We convert g to mg

14 g. 1000mg / 1 g = 14000 mg

He took 14000 miligrams of antibiotic in 2 weeks

Explanation:

Step 1: Data given

Mass of one pill = 0.250 grams = 250 miligrams

The patient takes one pill every 6 hours

Step 2: Calculate the number of pills per day

1 Day = 24 hours

Every 6 hours = 1 pill

Every 24 hours = 4 * 1 pill = 4 pills / day

Step 3: Calculate the number of pills for 2 weeks

2 weeks = 14 days

This means in 14 days he takes 4*14 = 56 pills

Step 4: Calculate the mass of the pills

1 pill has a mass of 0.250 grams

56 pills have a mass of 56 * 0.250 grams = 14 grams

14 grams = 14000 miligrams

He took 14000 miligrams of antibiotic in 2 weeks
