The Proportion Calculator is a dedicated tool designed to solve and verify proportional relationships between quantities. Proportions are equations that express two ratios or fractions as equivalent, playing a pivotal role in various mathematical and practical applications.

• Art: Maintaining scale in drawings or sculptures.
• Cooking: Adjusting recipe ingredients for serving sizes.
• Construction: Ensuring structural integrity with balanced measurements.
• Finance: Distributing investments or calculating returns.

Users input known values from a proportion, and the calculator determines the missing value. For instance, if given the proportion $\frac{x}{5} = \frac{3}{15}$, the calculator would identify $x$ as 1.

In scenarios where balance, scale, or equivalence is essential, the Proportion Calculator proves invaluable. It provides accurate solutions, ensuring that proportional relationships are understood, maintained, and utilized effectively.
