**Rule 16:
To divide three or more fractions, complete the
following three steps.**

**
**

**1.****Change the signs to sign and invert the fractions to the right of the signs.****2.****Multiply the numerators.****3.****Multiply the denominators.****4.****Reduce the results. (See Rule 10)****a.**- Factor the product of the numerators.
**b.**- Factor the product of the denominators.
**c.****Look for the fractions that have a value of 1.**

If you are still a skeptic, let's go through the routine
again.

Convert the whole number to a fraction so that the problem

can be written

Change the division signs to multiplication signs and invert the fractions to the right of the signs.

The right most fraction is undefined, the empty set, any expression that contains an undefined portion is itself undefined.
