Compare and contrast ratios and fractions?

RatiOS and fractions both represent relationships between numbers, but they do so in different ways. A ratio compares two quantities, indicating how many times one value contains or is contained by another (e.g., 3:2). In contrast, a fraction represents a part of a whole, expressed as a numerator over a denominator (e.g., 3/5). While fractions can be considered a specific type of ratio (where the denominator is the whole), ratiOS can encompass broader relationships beyond simple parts of a whole.
