Exercise 8 Page 143

When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different.

6.2

Practice makes perfect

When dividing real numbers, the quotient will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+) ÷ (+)=(+) & (+) ÷ (-)=(-) (-)÷ (-)=(+) & (-)÷ (+)=(-)In our case both numbers are negative, so the quotient will be positive.
