Understanding the Context

What Is a Ratio?

A ratio expresses a relationship between two quantities, showing how much of one value exists compared to another. It is written as A to B (or A:B), and it helps simplify comparisons in a clear, standardized way.

For example, if a classroom has 12 boys and 8 girls, the ratio of boys to girls is 12:8, which simplifies to 3:2—meaning for every 3 boys, there are 2 girls.

Example: In a group of 10 students, 4 play tennis — the part-to-whole ratio is 4:10 or simplified 2:5.

Health & Fitness
Body mass index (BMI) is a ratio of weight to height squared, aiding health assessments.
