答案： $\frac{5}{3}$ 4 0 $\frac{5}{2}$ $\frac{8}{15}$ $\frac{8}{9}$ $\frac{7}{3}$ 6 4 36 5 $\frac{34}{7}$ 14 $\frac{3}{2}$ 12 $\frac{2}{5}$ $\frac{10}{9}$ 14 $\frac{40}{3}$ $\frac{7}{6}$ $\frac{22}{3}$ 24 24 $\frac{45}{2}$

1. 列竖式计算。
$ 1.5 × 1.2 = $$ $ 2.88 ÷ 1.6 = $$
$ 16.9 ÷ 13 = $

答案： 1. 1.8 1.8 1.3

2. 脱式计算,能简算的要简算。
$ \frac{1}{2} + \frac{3}{10} - \frac{2}{5} $$ $ \frac{3}{4} - \frac{1}{2} + \frac{1}{4} $$
$ \frac{11}{12} - \frac{1}{3} - \frac{1}{4} $

答案： 2. $\frac{2}{5}$ $\frac{1}{2}$ $\frac{1}{3}$
