Answer 1

分析 根據(jù)分?jǐn)?shù)加、減、乘、除法的計(jì)算方法進(jìn)行計(jì)算，能用簡便方法計(jì)算的用簡便方法進(jìn)行計(jì)算．

解答

解：5.4+3$\frac{3}{5}$=9	0.5-$\frac{1}{3}$=$\frac{1}{6}$	$\frac{5}{12}$×$\frac{4}{5}$=$\frac{1}{3}$
5$\frac{5}{6}$÷3.5=$\frac{5}{3}$	12×（$\frac{1}{4}$+$\frac{1}{6}$-$\frac{1}{8}$）=3.5	17.32-5.66-4.34=7.32
4$\frac{3}{8}$+2.25+5$\frac{5}{8}$+7$\frac{3}{4}$=20	14$\frac{17}{27}$-（4$\frac{17}{27}$-3$\frac{17}{19}$）=13$\frac{17}{19}$	2.94×1.25+70.6×0.125=12.5
2006÷2006$\frac{2006}{2007}$=$\frac{2007}{2008}$

點(diǎn)評(píng) 本題考查了學(xué)生基本的計(jì)算能力，在計(jì)算中要細(xì)心．
