Multiplying and Dividing Fractions

Multiplying

When you multiply fractions, you multiply the numerators together, and the denominators together.

Example #1:

Reduce to lowest form; divide by\par highest common factor of 3

Lowest Form

Example #2:

A negative number times a negative number makes a positive number

Example #3:

A negative number divided by/over a negative number makes a positive number

The rules that you use when you multiply integers are also used when you multiply fractions.

Dividing

How do you divide ?

You first need to know how to find the reciprocal of a fraction.

Example #1

* Finding the reciprocal of a fractions is also know as “invertingthe fraction”

When you divide fractions, there are only two things to remember:

a) Invert (or find the reciprocal of) the second fraction only, and…

b) Multiply the fractions (which you already know how to do) !
