Ratios express the relationship between two quantities by comparing them in terms of their relative sizes. Ratios are typically written as ( \frac{a}{b} ), where ( a ) and ( b ) are two quantities being compared.

Fractions, on the other hand, represent a part-to-whole relationship. They express one or more parts of a whole. Fractions are also written as ( \frac{a}{b} ), where ( a ) represents the numerator (the number of parts being considered) and ( b ) represents the denominator (the total number of equal parts that make up the whole).

In summary, while both ratios and fractions involve expressing one quantity relative to another, ratios compare two quantities directly, whereas fractions represent parts of a whole.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
