Answer 1

分析 根據(jù)小數(shù)分數(shù)加減乘除法的計算方法解答．

解答 解：

3.6÷0.036=100	7÷19=$\frac{7}{19}$	3.7×0.1%=0.0037	72÷0.4=180	8.1+14=22.1
0.4×0.2=0.08	9-0.9=8.1	2.3-$\frac{4}{5}$=1.5	8-$\frac{1}{8}$×8=7	1-0.37=0.63
$\frac{3}{4}$÷$\frac{4}{3}$=$\frac{9}{16}$	$\frac{2}{5}$×$\frac{3}{8}$=$\frac{3}{20}$	$\frac{1}{2}$+$\frac{1}{3}$=$\frac{5}{6}$	4×$\frac{3}{8}$=1.5	8÷12.5%=64
$\frac{7}{15}$-$\frac{1}{3}$=$\frac{2}{15}$	5.3+2.67=7.97	1÷10%=10	0.3×0.4=0.12	1+0.2=1.2

點評 直接寫得數(shù)時，注意數(shù)據(jù)特點和運算符號，細心解答即可．
