Green Bridge Learning Resource For Ratio And Proportion

Overview

Ratio is how we compare quantities and share things out fairly, from mixing concrete to splitting a bill. Proportion is the partner idea: when two quantities change together at a fixed rate. Together they turn everyday sharing and scaling problems into quick, reliable calculations.

In this lesson you will write ratios in their simplest form, divide a quantity in a given ratio, and use proportional reasoning to scale recipes, maps and prices up or down. These methods reappear in similarity, rates and percentages, so they are well worth securing.
