Ratio Basics

A ratio is a mathematical comparison between two quantities of the same kind. It tells how many times one quantity contains another or how two amounts relate to each other. Written as a: b or a/b, ratios help simplify comparisons in an easy, universal form. For example, if the ratio of boys to girls in a class is 3: 2, it means that for every 3 boys, there are 2 girls.

Concept

Ratio

A ratio compares two quantities and tells us how many times one quantity is greater or smaller than the other. 💡 Exam Tip: Keep the order of terms consistent while writing ratios and proportions. In applications, identify whether the problem is direct proportion or inverse proportion before solving. ⚠️ Common Mistake: Students often invert one ratio accidentally or mix direct proportion with inverse proportion. 📌 Trigger: Order matters
