Answer 2

Answer:

$(i) \: \: \: \frac{21}{44} \div \frac{ - 11}{9} \\ = \: \: \: \frac{21}{44} \times \frac{9}{ - 11} \\ = \: \: \: \frac{189 \times - 1}{ - 484 \times - 1} \\ \boxed{ = \: \: \: \underline{ \underline{ \large \frac{ - 189}{484} }}} \\ \\ (ii) \: \: \: \frac{3}{25} \div \frac{4}{5} \\ = \: \: \: \frac{3}{25} \times \frac{5}{4} \\ = \: \: \: \frac{3}{ _{5 \: \: } \cancel{ 25}} \times \frac{ \cancel 5 _{ \: \: 1}}{4} \\ \boxed{ = \: \: \: \underline{ \underline{ \large \frac{3}{20} }}}$
