Ratio is often used to give a scale between two different things. Real life examples of this include a map scale, for example 1:25000 , a scale model of an object such as a model train in the scale 1:160 or a scale drawing.
The scale factor between two things is often given as a ratio in the form 1:n where n can be an integer, fraction, or a decimal. We can use the given ratio to calculate lengths of one thing based on the other. If the ratio of two items A:B is in the simplest form of 1:n then B is n times bigger (or smaller) than A .
For example, if a map has a scale of 1:100000 then two points which are 4cm apart on the map will be 4100000=400000cm or 4km apart in real life.
Looking forward, students can then progress to additional ratio worksheets and other ratio and proportion worksheets, for example a speed distance time worksheet or a direct proportion worksheet.
