a)

$\frac{20 \div 10}{30 \div 10 } = \frac{2}{3}$

$\frac{5}{6} different \: que \: \frac{2}{3}$

b)

$\frac{12 \div 3}{ - 21 \div 3} = \frac{4}{ - 7}$

donc -4/7=12/-21

c)

$\frac{63 \div 9}{ - 36 \div 9} = \frac{7}{ - 4}$

donc 63/-36=-7/4

d)

$\frac{ - 45 \div 5}{55 \div 5} = \frac{ - 9}{11}$

-9/11 different que 1/9
