1.每日速算。
$2.5×0.4=$1 $10-\frac {1}{4}=$$9\frac {3}{4}$ $\frac {1}{6}+\frac {2}{3}=$$\frac {5}{6}$ $3.2÷0.4=$8
$2.6+4.8=$7.4 $1\frac {3}{5}-\frac {1}{2}=$$1\frac {1}{10}$ $1.2×0.3=$0.36 $12÷5=$2.4

答案： $2.5×0.4=1$
$10-\frac {1}{4}=9\frac {3}{4}$
$\frac {1}{6}+\frac {2}{3}=\frac {5}{6}$
$3.2÷0.4=8$
$2.6+4.8=7.4$
$1\frac {3}{5}-\frac {1}{2}=1\frac {1}{10}$
$1.2×0.3=0.36$
$12÷5=2.4$

2.用竖式计算下面各题。
$13.3÷0.38=$35 $10.03-4.2=$5.83 $12.7×0.52=$6.604

答案： 13.3÷0.38=35

3.把下面的分数填在合适的圈中。
$10\frac {7}{8}$ $\frac {3}{4}$ $\frac {5}{3}$ $\frac {6}{6}$ $\frac {7}{9}$ $1\frac {5}{6}$

答案： 假分数：$\frac{5}{3}$，$\frac{6}{6}$
带分数：$10\frac{7}{8}$，$1\frac{5}{6}$
真分数：$\frac{3}{4}$，$\frac{7}{9}$

4.把下面的假分数化成带分数或整数。
$\frac {6}{5}= $$1\frac{1}{5}$ $\frac {35}{8}= $$4\frac{3}{8}$ $\frac {18}{18}= $1 $\frac {19}{2}= $$9\frac{1}{2}$

答案： $\frac{6}{5}=1\frac{1}{5}$
$\frac{35}{8}=4\frac{3}{8}$
$\frac{18}{18}=1$
$\frac{19}{2}=9\frac{1}{2}$
