二、在(
)里填上合适的数。(每空2分,共30分)
)+0.38=1.02 (
)-1.2=2.26 4.5-(
)=2.25
)÷4.4=0.5 2.34÷(
)=10% (
)×50%=0.7
$\frac{4}{7}+$(
)$=\frac{3}{4}$ $\frac{14}{3}-$(
)$=\frac{6}{5}$ (
)$-\frac{4}{5}=\frac{1}{6}$
$\frac{5}{18}×$(
)$=\frac{7}{12}$ $\frac{4}{3}÷$(
)$=\frac{8}{15}$ (
)$÷\frac{7}{15}=\frac{15}{4}$
$\frac{3}{11}÷$(
)$=\frac{2}{3}$ (
)$÷\frac{4}{15}=\frac{10}{3}$ (
)$×\frac{9}{4}=\frac{3}{8}$

答案

1.$0.64$
2.$3.46$
3.$2.25$
4.$2.2$
5.$23.4$
6.$1.4$
7.$\frac{5}{28}$
8.$\frac{52}{15}$
9.$\frac{29}{30}$
10.$\frac{21}{10}$
11.$\frac{5}{2}$
12.$\frac{7}{4}$
13.$\frac{9}{22}$
