Ratio and Proportion Fundamentals
📌 A ratio is a method of comparing quantities, exemplified by using one tea bag for every two cups of water ($1:2$).
🔗 Proportion refers to the consistency of two identical ratios, ensuring relationships remain the same when scaling up or down.
💡 For example, maintaining a $1:2$ ratio when making tea for five people requires $2.5$ tea bags to keep the proportion correct.

Application in Pharmacy Practice
⚕️ Ratio and proportion are vital in Pharmacology as they dictate safe medication dosages, balancing effectiveness and toxicity.
🔬 These principles are the crux of procedures like drug formulation and determining accurate drug dosages to guarantee patient safety.
🧪 The ability to translate mathematical figures into real-life drug preparation is a necessity for every pharmacist.
⚖️ In a practical example, reducing a formula from $1,000$ mL to $500$ mL requires proportionally reducing active ingredients (e.g., $1,000$ mg active substance becomes $500$ mg).

Key Points & Insights
➡️ Ratio and proportion are life-saving tools that underpin the world of medicine, extending beyond mathematics into fields like cooking and architecture.
➡️ Mastering these concepts allows pharmacists to efficiently adjust formulas, whether reducing, enlarging, or fortifying solution strengths.
➡️ Correctly applying these principles ensures precise drug dosages, making a significant impact on patient care and safety.
