$\frac{3}{10} + \frac{3}{5} =$　　$\frac{5}{9} \times 6 =$　　$\frac{14}{15} \div \frac{7}{25} = $　　
$1.5 × 0.5 = \frac{4}{3} - \frac{4}{9} = \frac{6}{7} \times \frac{1}{42} = \frac{1}{15} \times \frac{3}{4} = \frac{9}{10} \times \frac{1}{3} = 8 × 1.03 = $　　
$\frac{5}{6} \div \frac{25}{12} =$　　$4.8 ÷ 12 = \frac{7}{36} \div \frac{7}{3} = 7 - 23\% =$　　$\frac{7}{10} \div \frac{1}{2} =$　　$\frac{2}{3} \times \frac{9}{40} = $　　
$\frac{15}{16} + \frac{5}{4} =$　　$\frac{1}{9} \div 9 =$　　$\frac{4}{9} \div \frac{2}{5} = $　　
$0.96 ÷ 2 = 5.6 × \frac{1}{8} = \frac{9}{20} - \frac{3}{10} = \frac{5}{11} \div \frac{6}{11} = \frac{7}{10} \times \frac{12}{7} = 0.9 - \frac{9}{10} = 5 ÷ \frac{25}{6} = \frac{3}{22} \times 11 = \frac{3}{7} \times \frac{3}{10} = 350 ÷ 700 =$　　$0.35 + 1.45 = 200 × 16\% = $
