 As we know, in the dividing of decimal, we first express the decimal in term of fraction and then divides it, So

(i)\frac{7.75}{0.25}

\frac{7.75}{0.25}=\frac{\frac{775}{100}}{\frac{25}{100}}=\frac{775}{25}\times\frac{100}{100}=\frac{31}{1}=31

(ii)\frac{42.8}{0.02}

\frac{42.8}{0.02}=\frac{\frac{428}{100}}{\frac{2}{100}}=\frac{428}{2}\times\frac{100}{100}=214

(iii)\frac{5.6}{1.4}

\frac{5.6}{1.4}=\frac{\frac{56}{10}}{\frac{14}{10}}=\frac{56}{14}\times\frac{10}{10}=4
