Exercise 2 Page 246

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.

\underline{Same Sign} (+) \div (+) = (+) (-) \div (-) = (+) \underline{Different Signs} (+) \div (-) = (-) (-) \div (+) = (-)

In our case one number is positive and one number is negative, so the quotient will be negative.

\frac{4 2}{- 7}

Put minus sign in front of fraction

- \frac{4 2}{7}

Calculate quotient

- 6

We can verify this using a calculator.
