Let me use money as an example. You are familiar with US dollars and quarters? I hope so. There are 4 quarters in a dollar. The ratio of quarters to dollars is 4 to 1, written as 4:1 or 4/1. Another example: in a classroom there are 13 girls and 12 boys. The ratio of girls to boys is 13 to 12 or 13/12 or 1.083 girls for every boy. The ratio of boys to girls is 12/13 or 0.923 boys for every girl. A ratio establishes a relationship between the relative quantities of two or more variables.
