Find:

(a) \[\frac{7.75}{0.25}\]

(b)\[\frac{42.8}{0.02}\]

(c) \[\frac{5.6}{1.4}\]

Answer:

(a) \[\frac{7.75}{0.25}=7.75\div 0.25=\frac{775}{100}\div \frac{25}{100}\]

\[=\frac{775}{100}\times \frac{100}{25}=\frac{775}{25}=31\]

(b)\[\frac{42.8}{0.02}=42.8\div 0.02=\frac{428}{10}\div \frac{2}{100}\]\[=\frac{428}{10}\times \frac{100}{2}=214\times 10\]

= 2140

(c) \[\frac{5.6}{1.4}=5.6\div 1.4=\frac{56}{10}\div \frac{14}{10}\]

\[=\frac{56}{10}\times \frac{10}{14}=\frac{56}{14}=4\]
