Emma compared \[\dfrac{4}{6}\] and \[\dfrac{2}{5}\] by first comparing each fraction to \[\dfrac{1}{2}\]. Step 1: \[\dfrac{4}{6}\] is greater than \[\dfrac{1}{2}\]. Step 2: \[\dfrac{2}{5}\] is less than \[\dfrac{1}{2}\]. Step 3: So, \[\dfrac{4}{6} > \dfrac{2}{5}\] In which step did Emma make her first mistake?
