(i) $1\mathrm{by}\frac{1}{2}$

(ii) $5\mathrm{by}\frac{-5}{7}$

(iii) $\frac{-3}{4}\mathrm{by}\frac{9}{-16}$

(iv) $\frac{-7}{8}\mathrm{by}\frac{-21}{16}$

(v) $\frac{7}{-4}\mathrm{by}\frac{63}{64}$

(vi) $0\mathrm{by}\frac{-7}{5}$

(vii) $\frac{-3}{4}\mathrm{by}-6$

(viii) $\frac{2}{3}\mathrm{by}\frac{-7}{12}$

(ix) $-4\mathrm{by}\frac{-3}{5}$

(x) $\frac{-3}{13}\mathrm{by}\frac{-4}{65}$

Answer 1

$$\begin{gathered} \left(\mathrm{i}\right)1÷\frac{1}{2}=1\times \frac{2}{1}=2 \\ \left(\mathrm{ii}\right)5÷\frac{-5}{7}=5\times \frac{7}{-5}=-7 \\ \left(\mathrm{iii}\right)\frac{-3}{4}÷\frac{9}{-16}=\frac{-3}{4}\times \frac{-16}{9}=\frac{4}{3} \\ \left(\mathrm{iv}\right)\frac{-7}{8}÷\frac{-21}{16}=\frac{-7}{8}\times \frac{16}{-21}=\frac{2}{3} \\ \left(\mathrm{v}\right)\frac{7}{-4}÷\frac{63}{64}=\frac{7}{-4}\times \frac{64}{63}=\frac{-16}{9} \\ \left(\mathrm{vi}\right)0÷\frac{-7}{5}=0\times \frac{5}{-7}=0 \\ \left(\mathrm{vii}\right)\frac{-3}{4}÷-6=\frac{-3}{4}\times \frac{1}{-6}=\frac{1}{8} \\ \left(\mathrm{viii}\right)\frac{2}{3}÷\frac{-7}{12}=\frac{2}{3}\times \frac{12}{-7}=\frac{-8}{7} \\ \left(\mathrm{ix}\right)-4÷\frac{-3}{5}=-4\times \frac{5}{-3}=\frac{20}{3} \\ \left(\mathrm{x}\right)\frac{-3}{13}÷\frac{-4}{65}=\frac{-3}{13}\times \frac{65}{-4}=\frac{15}{4} \end{gathered}$$
