How do pharmacists use fractions?

Pharmacists use fractions in various ways, particularly in dosage calculations and compounding medications. For example, they may need to convert between different measurement units, such as milliliters to liters, or calculate the correct dosage based on a patient's weight. Fractions are also essential when determining the concentration of active ingredients in formulations or when diluting medications. Accurate use of fractions ensures proper medication management and patient safety.
