Question 4: Divide the following directed numbers. a) (-300) / (-6) b) (-1/2) / (1/4) c) (0.5) / (-0.25) / (-0.2) d) 200 / (1/4) - 0.2

A negative number divided by a negative number results in a positive number.

$$(-300) \div (-6) = 50$$

The solution is $\boxed{50}$.

$$-\frac{4}{2} = -2$$

The solution is $\boxed{-2}$.

$(0.5) \div (-0.25)$.

$$0.5 \div (-0.25) = \frac{0.5}{-0.25} = -2$$

$(-2) \div (-0.2)$.

$$(-2) \div (-0.2) = \frac{-2}{-0.2} = 10$$

The solution is $\boxed{10}$.

$$(200) \div \left(\frac{1}{4}\right) = 200 \times 4$$ $$200 \times 4 = 800$$

$$800 - 0.2 = 799.8$$

The solution is $\boxed{799.8}$.
