Proportional relationships in ratios have a few important features:
Same Ratio: The ratio between two amounts stays the same even as they change. For instance, if you have 2 apples for every 3 oranges, this ratio (2 to 3) remains true no matter how many fruits you have.
Direct Change: When one amount goes up, the other also goes up in a steady way. Think of it like a recipe: if you double the ingredients, you also double the number of servings.
Graphing: If you draw these relationships on a graph, they make a straight line that starts at the origin point (where the axes meet).
By knowing these features, you can tackle problems better. For example, this can help you figure out prices when they change but still keep the same ratios.
