Question

determine how many tablets will be needed to give the dosages.

1. tablets are labeled 0.01 mg. you must give 0.02 mg.
2. tablets are labeled 2.5 mg. you must give 5 mg.
3. tablets are labeled 0.25 mg. give 0.125 mg.
4. tablets are 0.5 mg. give 1.5 mg.
5. a dosage of 1.8 mg is ordered. tablets are 0.6 mg.
6. tablets available are 0.04 mg. you are to give 0.02 mg.
7. the dosage ordered is 3.5 mg. the tablets available are 1.75 mg.
8. prepare a dosage of 3.2 mg using tablets with a strength of 1.6 mg.
9. you have tablets labeled 0.25 mg and a dosage of 0.375 mg.

Explanation:

Step1: Use the formula Number of tablets = $\frac{Desired\ dosage}{Tablet\ strength}$

For each sub - question, we will apply this formula.

Step2: Solve 42

Desired dosage = $0.02$ mg, Tablet strength = $0.01$ mg. Number of tablets = $\frac{0.02}{0.01}=2$

Step3: Solve 43

Desired dosage = $5$ mg, Tablet strength = $2.5$ mg. Number of tablets = $\frac{5}{2.5}=2$

Step4: Solve 44

Desired dosage = $0.125$ mg, Tablet strength = $0.25$ mg. Number of tablets = $\frac{0.125}{0.25}=0.5$

Step5: Solve 45

Desired dosage = $1.5$ mg, Tablet strength = $0.5$ mg. Number of tablets = $\frac{1.5}{0.5}=3$

Step6: Solve 46

Desired dosage = $1.8$ mg, Tablet strength = $0.6$ mg. Number of tablets = $\frac{1.8}{0.6}=3$

Step7: Solve 47

Desired dosage = $0.02$ mg, Tablet strength = $0.04$ mg. Number of tablets = $\frac{0.02}{0.04}=0.5$

Step8: Solve 48

Desired dosage = $3.5$ mg, Tablet strength = $1.75$ mg. Number of tablets = $\frac{3.5}{1.75}=2$

Step9: Solve 49

Desired dosage = $3.2$ mg, Tablet strength = $1.6$ mg. Number of tablets = $\frac{3.2}{1.6}=2$

Step10: Solve 50

Desired dosage = $0.375$ mg, Tablet strength = $0.25$ mg. Number of tablets = $\frac{0.375}{0.25}=1.5$
