    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

    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
