Write the target unit first
For a unit-conversion exercise asking for milligrams, write mg beside the answer line. To convert 0.75 g, multiply by 1,000 mg per gram. The grams cancel and the result is 750 mg. Write units throughout so you can spot an inverted conversion factor.
Mark the difference between per day and per dose
In a fictional worksheet, 600 mg per day divided into three equal doses gives 200 mg per dose. Write the daily total and number of doses separately, then confirm that your final unit matches what the question asks for. Use this approach for classroom practice with your course’s rounding rules.
Try it yourself
A fictional worksheet gives a daily total of 480 mg divided into four equal doses. What is the amount per dose?
Show the answer
480 mg per day ÷ 4 doses per day = 120 mg per dose. Multiplying 120 by four returns the original daily total.
