Ratios, Proportions & Dilutions (Applied Math)

Course Overview

The Ratios, Proportions & Dilutions (Applied Math) course gives learners a clear, exam-focused mastery of how to handle ratios, direct and inverse proportion, dilution, concentration, mixtures, and word problems with speed and confidence. This course is designed for IGCSE and O Level Mathematics learners who want strong concept clarity, accurate mathematical language, and the ability to solve both structured and real-life scenario questions using mark-scheme-ready methods.

Using structured explanations, several worked examples, exam tips, interactive quizzes, and high-quality LearnStalk explainer videos, learners will build fast recall, strong application skills, and reliable exam technique. Whether you are revising for finals, preparing for mock exams, or strengthening your foundation for advanced topics like rates and algebra, this course guides you step by step from basics to exam mastery.

What You Will Learn

• Understand ratio language and notation, simplify ratios correctly, and apply part-to-part and part-to-whole reasoning in exam questions.
• Solve sharing problems using the parts method and avoid common ratio-order mistakes.
• Master proportions using equivalent ratios, cross-multiplication, and unit methods.
• Distinguish direct vs inverse proportion using correct mathematical forms.
• Solve dilution and concentration problems using correct exam logic and structured setup methods.
• Handle unit conversions, mixtures, and real-life applications with clear working and correct units.
• Develop strong word-problem translation skills and perform quick reasonableness checks.

Why This Course Matters

Many learners lose marks in ratios, proportions, and dilutions because they memorize rules without understanding the setup. In IGCSE/O Level exams, questions test whether you can interpret context, choose the correct relationship, and show method. This course trains you to recognize patterns, apply structured steps, and produce answers that are fast, accurate, and mark-scheme-ready.
