Answer 1

Answer:

-4/6

10/-14

12/18

20/160

Answer 2

$\frac{ - 2}{3} \: \times \: \frac{2}{2} \: = \: \frac{ - 4}{6 }</p><p> \\ \frac{ - 2}{3} \: \times \: \frac{3}{3 } \: = \: \frac{ - 6}{9} </p><p> \\ \frac{ - 2}{3} \: \times \: \frac{4}{4} \: = \: \frac{ - 8}{12}$

$\frac{5}{ - 7} \: \times \: \frac{2}{2} \: = \: \frac{10}{ - 14} \\ \frac{5}{ - 7} \: \times \: \frac{3}{3} \: = \: \frac{15}{21} \\ \frac{5}{ - 7} \: \times \: \frac{4}{4} \: = \: \frac{20}{28}$

$\frac{ - 6}{ - 9} \: \times \: \frac{2}{2} \: = \: \frac{12}{18} \\ \frac{ - 6}{ - 9} \: \times \: \frac{3}{3} \: = \: \frac{18}{27} \\ \frac{ - 6}{ - 9} \: \times \: \frac{4}{4} \: = \: \frac{24}{36}$

$\frac{10}{80} \: \times \: \frac{2}{2} \: = \: \frac{20}{160 } \\ \frac{10}{80} \: \times \: \frac{3}{3} \: = \: \frac{30}{240} \\ \frac{10}{80} \: \times \: \frac{4}{4} \: = \: \frac{40}{320}$
