Available tablets: 100 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 100 mg tablets are needed to make 250 mg of ciprofloxacin.
Set up a proportion to solve for the unknown number of tablets (X):
100 mg/tablet = 250 mg/X tablets
Cross-multiplying gives us:
100 mg x X tablets = 250 mg x 1 tablet
Simplifying:
100X = 250

Explanation
Given:
Total daily dose: 300 mg of propylthiouracil per day
Number of doses per day: 3 doses
Available tablets: 50 mg tablets
Steps to solve:
Determine the dose per administration:

Determine the number of tablets per dose:
Find how many 50 mg tablets are needed to make 100 mg of propylthiouracil.
Set up a proportion to solve for the unknown number of tablets (X):
50 mg/tablet = 100 mg/X tablets
Cross-multiplying gives us:
50 mg x X tablets = 100 mg x 1 tablet
Simplifying:
50X = 100
Solving for X:
X = 100 / 50 = 2 tablets
