Answer 1

$\sf{1.) \frac{8}{5} \div \frac{2}{3}} \\ \\ \implies \sf{ \frac{8}{5} \times \frac{3}{2} } \\ \\ \implies \sf{ \frac{8 \times 3}{5 \times 2} } \\ \\ \implies \sf{ \cancel \frac{24}{10} = \green{\boxed{ \orange{ \frac{12}{5} }} }}$

$\sf{ 2.)\frac{18}{25} \div \bigg( \frac{ - 72}{75} \bigg)} \\ \\ \implies \sf{ \frac{18}{25} \times \bigg( \frac{ - 75}{72} \bigg)} \\ \\ \implies \sf{ \frac{18 \times - 75}{25 \times 72} } \\ \\ \implies \sf{ \cancel \frac{ -1350 }{ 1800} } = \green{\boxed{\sf{ { \orange{\frac{ - 27}{36} }}}}}$

$\sf{ 3.)\frac{ - 125}{64} \div \frac{50}{16} } \\ \\ \implies \sf{ \frac{ - 125}{24} \times \frac{16}{50} } \\ \\ \implies \sf{ \frac{ - 125 \times 16}{64 \times 50} } \\ \\ \implies \sf{ \frac{ - 20 \cancel{00}}{32 \cancel{00}} = \cancel\frac{ - 20}{34} = \cancel \frac{10}{16} = \green{ \boxed{ \orange{ \frac{ - 5}{8} }}}}$

_____

$\sf{4.) \frac{ - 512}{441} \div \frac{ - 1024}{21} } \\ \\ \implies \sf{ \frac{ - 512}{441} \times \frac{ 21}{1024} } \\ \\ \implies \sf{ \frac{ 512}{441} \times \frac{ 21}{1024} } \\ \\ \implies \sf{ \frac{512 \times 21}{441 \times 1024} } \\ \\ \implies \sf{ \cancel\frac{67032}{451584} = \cancel \frac{33516}{225792} = \cancel\frac{16758}{112896} } \\ \\ \sf{ = \cancel \frac{8479}{56445} =\cancel \frac{4238}{28224} = \green{ \boxed{ \orange{\frac{2119}{14113} }}}}$
