How to Divide fractions by "flipping & dipping"

The instructor in this video gives a tutorial on how to divide fractions by "flipping & dipping" method. He says that to divide two fractions we need to follow two steps of flipping and dipping. He says to write the first fraction as it self and flip the second fraction and write it beside. Now he says that instead of dividing we are dipping and multiplying both the fractions which results in the division of the original fractions. Now after multiplying the fractions we get a fraction which can be reduced it possible, resulting in the answer. In this video the author shows how to divide fractions by a simple "flipping & dipping" method.
