Dividing Rational Numbers RULES: RULES: 1. When multiplying or dividing integers with the same signs, the answer will be Positive.

RULES: RULES: 1. When multiplying or dividing integers with the same signs, the answer will be Positive. 2. When multiplying or dividing integers with different signs, the answer will be Negative. Dividing Rational Numbers

Rules for Dividing Rational Numbers: Dividing two integers with the same signs: Negative Negative = Positive Positive Positive = Positive + = - + = ÷ ÷ + + ÷ ÷ - +

Rules for Dividing Rational Numbers: Dividing two integers with different signs: Negative Positive = Negative Positive Negative = Negative + = - - = ÷ ÷ ÷ ÷ - - +

Try some. -48 ÷ 6= 24 ÷ -6= -63 ÷ -9= Find the quotient. Remember the rules for dividing rational numbers.

Try some. -48 ÷ 6= ÷ -6= ÷ -9=

Dividing Rational Numbers

Use the same rules for multiplying as dividing. [Remember that division by zero is undefined.] -32 ÷ 8 = -48 ÷ (-6) = -56 ÷ (-4) = -140 ÷ 5 = Dividing Rational Numbers
