Answer 1

$Simplify: \\ </p><p>(i) \frac{4}{9} ÷ \frac{ - 5}{12} \\ </p><p>(ii) \frac{ - 65}{14} ÷ \frac{13}{7} \\ </p><p>(iii) \frac{ - 12}{7} ÷(-18) \\ \\ solution \\( i) = \frac{4}{9} ÷ \frac{ - 5}{12} \\ \\ = \frac{4}{9} \times \frac{12}{ - 5} \\ \\ = \frac{4}{3} \times \frac{4}{ - 5} \\ \\ = \frac{16 \times ( - 1)}{ - 15 \times ( - 1)} \\ \\ = \frac{ - 16}{15} \: \: answer... \\ \\ (ii) = \frac{ - 65}{14} ÷ \frac{13}{7} \\ \\ = \frac{ - 65}{14} \times \frac{7}{13} \\ \\ = \frac{ - 5}{2} \times \frac{1}{1} \\ \\ = \frac{ - 5}{2} = - 2.5 \: \: \: answer... \\ \\ (iii) = \frac{ - 12}{7} ÷(-18) \\ \\ = \frac{ - 12}{7} \times \frac{1}{ - 18} \\ \\ = \frac{ 2}{7} \times \frac{1}{3} \\ \\ = \frac{2}{21} \: \: answer...$
