Ratio Concepts & Applications
Simplifying Ratios
Divide all terms in a ratio by their greatest common divisor to get the simplest form. For example, 8:12 simplifies to 2:3.
Cooking & Recipes
Ratios are essential in cooking for scaling recipes. A 3:2:1 ratio of flour:butter:sugar can be scaled up or down while maintaining proportions.
Maps & Scale Models
Scale ratios like 1:1000 mean 1 unit on the map equals 1000 units in reality. Useful for architecture, modeling, and cartography.
Financial Ratios
Ratios are used in finance for analysis, such as debt-to-equity ratio, current ratio, and price-to-earnings ratio for investment decisions.
