What fraction represents one-half?

One-half is represented by the fraction 1/2. This means that if you divide something into two equal parts, one of those parts represents one-half of the whole. For example, if you have a pizza and you cut it into two equal slices, taking one of those slices would mean you have one-half of the pizza.

The fraction 1/2 consists of the numerator (the top number), which is 1, indicating how many parts you have, and the denominator (the bottom number), which is 2, indicating how many equal parts the whole is divided into. This clearly illustrates the concept of having one part out of two equal parts, making it the correct representation of one-half.
