Algebra Rule 3


Dividing the numerator equals multiplying the denominator

```{\left({a \over c}\right) \over b} = {a \over bc}```
Description:

If you divide the numerator by a particular number, it has the same effect on the fraction's overall value as if you multiply the denominator by that same number. A division above equals a multiplication below.

```{ \left({1 \over 5}\right) \over 2} = {1 \over 10} = {1 \over (2*5)}```

A little bit about algebrarules.com

Algebra rules is a project by two of the folks who run The Autodidacts.

A couple of autodidact math enthusiasts, we were looking for all the rules of basic algebra concisely presented in one place. We couldn’t find such a place, so we made Algebrarules.com

These simple rules — applied with a pinch of imagination and a dash of arithmetic — can divide, conquer, and solve just about any practical algebra problem.
