If the whole is divided into 2 equal sized pieces, each piece is ​one half of the whole. If the whole is divided into 4 equal sized pieces, each piece is one fourth of the whole. video https://cdn.kastatic.org/googleusercontent/LyG6K0bT326kPgOXP7kAaNxElGIn_9PZ3skwsuSsBjjm9MKXyCO6WwxTyCSuQdvcTW2WEOH8cye4YOpyBWLnre0 Halves and fourths When a whole is divided into equal size pieces, the pieces are fractions of the whole.
