Divide: Flip the second fraction, then multiply.
One-half ร one-third
โ Multiply: 1 ร 1 = 1 (top), 2 ร 3 = 6 (bottom)

โ Flip one-fourth to get four over one
โ Multiply: one-half ร four over one = Four-halves = Two
It shows how much we have when we take part of a part, or how many groups we can make.
