Nelda baked two kinds of pasta in pans. Each pan was the same size. She sliced one pan of pasta into 4 equal pieces. She sliced the other pan into 6 equal pieces. How can the pans of pasta now be sliced so that both pans have the​ same-sized pieces? If Nelda has served 8 pieces from 1 pan so​ far, what fraction of 1 pan has she​ served?
