8. Another way to look at division of fractions: Try to make the denominator a WHOLE #. Whatever you do to the DENOMINATOR you MUST do to the NUMERATOR.

9. Sign of a quotient Same signs: (-)/(-) = + or (+)/(+)=+ –take quotient of absolute values –answer is POSITIVE Different signs: (-)/(+) = - or (+)/(-) = - –take quotient of absolute values –answer is NEGATIVE

10. Practice Find the quotient.
