This document discusses equivalent fractions. It begins by defining fractions and their numerator and denominator. It then explains that equivalent fractions are fractions that represent the same quantity or amount, even if written differently. Two fractions are equivalent if their numerators and denominators are multiplied by the same number. The document provides examples of determining equivalent fractions using a fraction wall or by multiplying the numerator and denominator by the same number. It also gives examples of finding a missing numerator or denominator in an equivalent fraction pair.
