2.

A)

$\frac{1}{3} \times 6 \\ = \frac{1}{3} \times \frac{6}{1} \\ = \frac{6}{3} \\ = 2$

B)

$\frac{2}{( - 3)} \times 12 \\ = \frac{2}{( - 3)} \times \frac{12}{1} \\ = \frac{24}{ - 3} \\ = - 8$

C)

$( - \frac{3}{7} ) \times 7 \\ = ( - \frac{3}{7} ) \times \frac{7}{1} \\ = - \frac{21}{7} \\ = - 3$

D)

$\frac{3}{4} \times 8 \\ = \frac{3}{4} \times \frac{8}{1} \\ = \frac{24}{4} \\ = 6$

E)

$\frac{5}{3} \times ( - 12) \\ = \frac{5}{3} \times \frac{ - 12}{1} \\ = - \frac{60}{3} \\ = - 20$

F)

$( - \frac{1}{6} ) \times ( - 18) \\ = ( - \frac{1}{6} ) \times \frac{( - 18)}{1} \\ = \frac{18}{6} \\ = 3$

3.

A)

$\frac{2}{9} \times \frac{9}{2} \\ = \frac{18}{18} \\ = 1$

B)
