Understanding ratios as fractions is crucial for comparing quantities in mathematics. This guide explains how to convert ratios to fraction form, ensuring they are dimensionless and composed of integers. It also covers simplifying ratios by finding the greatest common divisor (GCD) and applying these concepts to real-world problems, such as dividing a loaf of bread or categorizing movies in a cinema.

Understanding Ratios as Fractions

Ratios are an essential mathematical concept used to compare two or more quantities. When expressed as fractions, ratios offer a clear representation of this comparison. A ratio of X to Y, denoted as X:Y, can be equivalently written as the fraction X/Y, where X is the numerator and Y is the denominator. This form is particularly useful for understanding proportions and for performing calculations that involve comparisons.

Converting Ratios to Fractions: Basic Examples

To demonstrate the conversion of ratios to fractions, consider simple examples: a ratio of 1 to 2 is equivalent to the fraction 1/2, a ratio of 5 to 6 corresponds to the fraction 5/6, a ratio of 3 to 2 is represented as 3/2, and a ratio of 13 to 12 is written as 13/12. In each instance, the first number of the ratio becomes the numerator, and the second number becomes the denominator in the fraction form.
