答案： 1 $\frac{1}{10}$ $\frac{1}{8}$ $\frac{2}{3}$ $\frac{4}{15}$ $\frac{5}{26}$ $\frac{1}{35}$ $\frac{2}{27}$ $\frac{1}{2}$ $\frac{5}{9}$ $\frac{4}{11}$ $\frac{4}{5}$ $\frac{9}{28}$ $\frac{1}{10}$ $\frac{1}{6}$ $\frac{6}{25}$ $\frac{3}{5}$ $\frac{1}{9}$ $\frac{2}{11}$ $\frac{2}{21}$ $\frac{1}{21}$ $\frac{3}{5}$ $\frac{2}{27}$ 1

1. 列竖式计算。
$ 5.04 ÷ 1.4 = $$ $ 36.6 ÷ 6.1 = $$
$ 13.2 × 2.1 = $

答案： 1.3.6 6 27.72

2. 脱式计算,能简算的要简算。
$ \frac{1}{2} + \frac{7}{10} - \frac{9}{10} $$ $ \frac{9}{16} - \frac{3}{16} + \frac{1}{4} $$
$ \frac{4}{5} + \left( \frac{1}{5} - \frac{2}{15} \right) $

答案： 2.$\frac{3}{10}$ $\frac{5}{8}$ $\frac{13}{15}$
