Ratio and proportion are two fundamental concepts in mathematics that have many applications in real-world scenarios. A ratio is a comparison of two quantities, often expressed in the form of a fraction, while a proportion is the equality of two ratios.


For example, a ratio of 3:4 represents the relationship between three and four, while a proportion of 6:8 = 3:4 represents the relationship between six and eight, which is equivalent to the relationship between three and four.


Ratio and proportion are used in various fields, such as finance, engineering, science, and medicine. In finance, they are used to calculate interest rates and exchange rates. In engineering, they are used to determine the strength and weight of materials. In science, they are used to express and calculate the concentration of solutions. In medicine, they are used to calculate drug dosages and create medical solutions.


To solve problems involving ratio and proportion, it is essential to understand the relationship between the terms and use them to create an equation. Reducing ratios to their simplest form is also crucial in making calculations easier and comparing different ratios. Cross-multiplying is often used when solving proportions, which involves multiplying the numerator of one ratio by the denominator of the other ratio and vice versa.
