tablets
Explanation & Rationale
To calculate the number of tablets, we need to use the formula: Number of tablets = Dose (mg) / Strength (mg/tablet) First, we need to convert the dose and the strength from micrograms (mcg) to milligrams (mg) by dividing by 1,000. In this case, 0.075 mg is equivalent to 75 mcg and 50 mcg is equivalent to 0.05 mg. Plugging in the given values, we get: Number of tablets = 75 mcg / 50 mcg Simplifying, we get: Number of tablets = 1.5 Rounding to the nearest tenth, we get: Number of tablets = 1.5
