Representation: Ratios can be represented in different ways, such as using a colon (e.g. 3:2), as a fraction (e.g. 3/2), or using the word "to" (e.g. 3 to 2).
Application: Ratios are used in various real-life scenarios, such as in cooking recipes, financial calculations, and understanding proportions.
Proportions: Understanding ratios is important for understanding proportions, where two ratios are set equal to each other.
Example
Suppose you have a bag of fruit containing 5 apples and 3 oranges. The ratio of apples to oranges is 5:3. This ratio can be represented as the fraction 5/3.
Select and use appropriate statistical methods to analyze data.
Discuss and understand the correspondence between data sets and their graphical representations, especially histograms, stem-and-leaf plots, box plots, and scatterplots.
