6. A Few Words About Nothin (i.e. Zero)

In a previous post, we dabbled a bit in ratios.  However, I failed to mention at that time that the denominator, the number below the line, the second number of a ratio, shan't be a Zero. Many word problems dealing with ratios may provide a word problem having a ratio of a/b and then quickly add where b is not equal to zero.

The reason is this:  you cannot divide a number by Zero.  It's not allowed, it's against the law of mathematics, I'm sure it violates some federal law and maybe even the Constitution, and besides, it just ain't fittin.  Only terrorists divide by zero.

If you find yourself faced with a ratio or fraction type problem where the denominator is zero...STOP!   Put down your pencil.  And call the authorities immediately.
