(i) 12 ÷ \(\frac{3}{4}\) = 12 ×\(\frac{4}{3}\) = 16
(ii) 14 ÷ \(\frac{5}{6}\) = 14 ×\(\frac{6}{5}\) = \(\frac{84}{5}\)
(iii) 8 ÷\(\frac{7}{3}\) = 8 × \(\frac{3}{7}\) = \(\frac{24}{7}\)
(iv) 4 ÷ \(\frac{8}{3}\) = 4 × \(\frac{3}{8}\)= \(\frac{3}{2}\)
(v) 3 ÷ 2 \(\frac{1}{3}\) = 3 ÷ \(\frac{7}{3}\) = 3 × \(\frac{3}{7}\) = \(\frac{9}{7}\)
(vi) 5 ÷ 3 \(\frac{4}{7}\) = 5 ÷ \(\frac{25}{7}\) = 5 × \(\frac{7}{25}\) = \(\frac{7}{5}\)
