CI Proportion calculator

This calculator solves for a missing value in a proportional relationship and can enlarge or shrink a given ratio. It is designed for students, cooks, designers, and anyone who needs to work with ratios in practical situations like adjusting recipes, calculating dimensions, or solving math problems.

Missing Value Calculation: Enter any three known values from a proportion (A:B = C:D) to instantly compute the fourth. The tool uses the cross-multiplication method to ensure accuracy.

Ratio Scaling: Multiply or divide both parts of a ratio by a number to scale it up or down while maintaining the original relationship. This is useful for adapting ingredient quantities or resizing designs.

Visual Representations: View the calculated ratio as a pie chart, bar chart, and rectangle diagram. These graphics make it easier to grasp the comparative sizes of the numbers involved.

Direct Input and Output: The interface requires only the necessary numerical entries and presents the answer clearly, without unnecessary steps or complex instructions.
