There is a drug order for 75 mg of drug.The drug is available in 30-mg scored tablets. How many tablets should be administered?

rosijanka [135]

Answer:

Assuming that tablets can be devided, $2\frac{1}{2}$ tablets are needed.

Assuming that tablets cannot be devided, $3$ tablets are needed.

Step-by-step explanation:

To find the total number of tablets that covers the order, we can divide the order total mg over each tablet mg.

$\frac{TotalOrderMg}{SingleTabletMg} = \frac{75 mg}{30 mg} = 2.5 mg$

Assuming that tablets can be devided, we can express the previous result in fractions

$2.5 = \frac{25}{10} = \frac{5}{2} = \frac{4}{2} + \frac{1}{2} = 2\frac{1}{2}$

Assuming that tablets cannot be devided, we need to cover 2 tables and a half, then we will need 3 tables.
