Question

13．直接寫出得數(shù)．

370+240=	1000-637=	0.23÷100=	5.7÷0.1=
52÷104=	2.7×3=	1-0.89=	$\frac{1}{2}$-$\frac{1}{5}$=
3.2×0.3=	6-0.73=	5.1÷0.3=	20÷$\frac{4}{5}$=
3÷$\frac{1}{6}$=	$\frac{8}{7}$÷$\frac{4}{7}$=	$\frac{9}{8}$÷$\frac{8}{9}$=	$\frac{9}{10}$×$\frac{5}{6}$=
$\frac{1}{100}$÷$\frac{1}{10}$=	$\frac{1}{3}$+$\frac{1}{4}$=	$\frac{2}{5}$+40%=	3+0.22=

Answer 1

分析 根據(jù)整數(shù)、分數(shù)和小數(shù)四則運算的計算法則進行計算即可．

解答 解：

370+240=610	1000-637=363	0.23÷100=0.0023	5.7÷0.1=57
52÷104=0.5	2.7×3=8.1	1-0.89=0.11	$\frac{1}{2}$-$\frac{1}{5}$=0.3
3.2×0.3=0.96	6-0.73=5.27	5.1÷0.3=17	20÷$\frac{4}{5}$=25
3÷$\frac{1}{6}$=18	$\frac{8}{7}$÷$\frac{4}{7}$=2	$\frac{9}{8}$÷$\frac{8}{9}$=$\frac{81}{64}$	$\frac{9}{10}$×$\frac{5}{6}$=$\frac{3}{4}$
$\frac{1}{100}$÷$\frac{1}{10}$=$\frac{1}{10}$	$\frac{1}{3}$+$\frac{1}{4}$=$\frac{7}{12}$	$\frac{2}{5}$+40%=0.8	3+0.22=3.04

點評 此題考查了整數(shù)、分數(shù)和小數(shù)四則運算的計算法則的運用．
