Answer 1

分析 根據(jù)整數(shù)、分?jǐn)?shù)、小數(shù)的計(jì)算方法解答．

解答 解：

7÷0.01=700	10.2+8%=10.28	2.9×101=292.9	6.5+9.5+3.5=19.5	0.7×0.4÷0.7×0.4=0.16
31725-0÷（9-4825 ）=31725	0.88+0.12=1	452+98=550	0.25×0.4=0.1	1.25×8=10
640÷16=40	5.01-1.8=3.21	$\frac{2}{5}$÷$\frac{1}{5}$=2	$\frac{3}{4}$-$\frac{1}{4}$=$\frac{1}{2}$	$\frac{6}{7}$-$\frac{6}{7}$=0
$\frac{1}{3}$-$\frac{1}{4}$=$\frac{1}{12}$	$\frac{5}{9}$×$\frac{1}{5}$=$\frac{1}{9}$	12+$\frac{1}{4}$=12$\frac{1}{4}$	$\frac{1}{2}$+$\frac{1}{3}$=$\frac{5}{6}$	8-$\frac{7}{8}$=7$\frac{1}{8}$

點(diǎn)評(píng) 直接寫(xiě)得數(shù)時(shí)，注意數(shù)據(jù)特點(diǎn)和運(yùn)算符號(hào)，細(xì)心解答即可．
