-3/7 : 4/12=
41/3 : 22/5=
15/11 : 4/5=
17/5 : 4/3=
1/2 : 1/3 =
-19/8 . -12/7=
(12/5) . (7/4) : 3/2=
(9/8 . 5/4) : (1/4 . 11/3)=

Answer 1

$- \frac{3}{7} \div \frac{4}{12} = - \frac{3}{7} \times \frac{12}{4} = \frac{ - 36}{28}$

$\frac{41}{3} \div \frac{22}{5} = \frac{41}{3} \times \frac{5}{22} = \frac{205}{66}$

$\frac{15}{11} \div \frac{4}{5} = \frac{15}{11} \times \frac{5}{4} = \frac{75}{44}$

$\frac{17}{5} \div \frac{4}{3} = \frac{17}{5} \times \frac{3}{4} = \frac{51}{20}$

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

$- \frac{19}{8} \times - \frac{12}{7} = \frac{228}{56}$
