(xi) 0.18
(xii) $\frac{7}{125}$

Answer 1

$$\begin{gathered} \left(\mathrm{i}\right)\frac{7}{25}=\frac{7}{25}\times 100 \\ =\frac{700}{25}=28\% \\ \left(\mathrm{ii}\right)\frac{14}{625}=\frac{14}{25\times 25}\times 100 \\ =\frac{1400}{625} \\ =2.24\% \\ \left(\mathrm{iii}\right)\frac{5}{8}=0.625\times 100 \\ =62.5\% \\ \left(\mathrm{iv}\right)0.8=\frac{8}{10}\times 100 \\ =80\% \\ \left(\mathrm{v}\right)0.005=0.005\times 100 \\ =0.5\% \\ \left(\mathrm{vi}\right)3:25=\frac{3}{25}\times 100 \\ =\frac{300}{25} \\ =12\% \\ \left(\mathrm{vii}\right)11:80=\frac{11}{80}\times 100 \\ =\frac{1100}{80} \\ =13.75\% \\ \left(\mathrm{viii}\right)111:125=\frac{111}{125} \\ =0.888\times 100 \\ =88.8\% \\ \left(\mathrm{ix}\right)13:75=\frac{13}{75} \\ =0.1733\times 100 \\ =17.33\% \\ \left(\mathrm{x}\right)15:16=\frac{15}{16} \\ =0.9375\times 100 \\ =93.75\% \\ \left(\mathrm{xi}\right)0.18=\frac{18}{100} \\ =\frac{18}{100}\times 100 \\ =18\% \\ \left(\mathrm{xii}\right)\frac{7}{125}=0.056 \\ =0.056\times 100 \\ =5.6\% \end{gathered}$$
