Find:

(a) \[7\div 3.5\]

(b) \[36\div 0.2\]

(c)\[3.25\div 0.5\]

(d) \[30.94\div 0.7\]

Answer:

(a)        \[7\div 3.5=7\div \frac{35}{10}=7\times \frac{70}{35}=2\]

(b)        \[36\div 0.2=36\div \frac{2}{10}=36\times \frac{10}{2}\]               = 18 × 10 = 180

(c)         \[3.25\div 0.5=\frac{325}{100}\div \frac{5}{10}=\frac{325}{100}\times \frac{10}{5}\]

\[=\frac{65}{10}=6.5\]

(d)        \[30.94\div 0.7=\frac{3049}{100}\div \frac{7}{10}\]

=\[\frac{3049}{100}\times \frac{10}{7}=\frac{442}{10}\]

= 44.2
