I explain two situations where we can divide fractions without using the common "rule" for fraction division, but just fraction number sense and mental math.

The first is when we divide fractions by whole numbers, because we can think of pie pieces shared evenly between so many people, such as 6/10 divided by 3.

The other situation is a fraction divided by a fraction when the quotient is a whole number. You can think "How many times does the divisor 'fit' into the dividend?" For example , 4/7 divided by 2/7 gives the quotient (answer) of 2, because 2 x (2/7) is 4/7.

These ideas are also explained (along with practice problems) in my book Math Mammoth Fractions 2 at http://www.mathmammoth.com/fractions_2.php - available both as an inexpensive download (\$5.75) and as a printed copy.
