Answer/Step-by-step explanation:

1.a)(iv). $\frac{1}{6} + (-\frac{7}{8}$

Positive multiplied by negative = negative

$\frac{1}{6} - \frac{7}{8}$

$\frac{4 - 21}{24} = \frac{-17}{24} = -\frac{17}{24}$

2a.) 73.48 +(-37.3)

$Note: + * - = -$

73.48 - 37.3 = 36.18

3c.) $3\frac{3}{4}$ ÷ $(-4\frac{2}{7})$

Convert to proper fraction

$\frac{15}{4}$ ÷ $(-\frac{30}{7})$

Change ÷ to × and flip the fraction on your right upside down

$\frac{15}{4} * (-\frac{7}{30})$

$-\frac{15*7}{4*30}$

$-\frac{1*7}{4*2} = -\frac{7}{8}$

3d.) -52.25 ÷ (-5.5) = $\frac{-52.25}{-5.5}$

(Note: - ÷ - = + )

$\frac{-52.25}{-5.5} = 9.5$
