Desired dose of ibuprofen: 20 mg
Concentration of ibuprofen drops: 50 mg/1.25 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
20 mg / Volume = 50 mg/1.25 mL
Step 3: Solve for the unknown volume:
Volume = 20 mg / (50 mg/1.25 mL)
Step 4: Calculate the volume:
Volume = 20 mg / 40 mg/mL
Volume = 0.5 mL

1 mg = 1000 mcg
Prescribed dose: 0.4 mg Converted to mcg: 0.4 mg x 1000 = 400 mcg
Available tablets: 200 mcg each
Next, we divide the prescribed dose by the strength of the available tablets:
400 mcg / 200 mcg per tablet = 2 tablets
