18．直接寫(xiě)出得數(shù)．

2.4+2.36=	4.5÷0.9=	0.8×0.5=	0÷0.99=
4.02+$\frac{3}{5}$-0.02=	$\frac{6}{7}$÷$\frac{9}{14}$=	$\frac{2}{7}$-$\frac{1}{6}$=	3.5×$\frac{4}{5}$=

Answer 1

分析 根據(jù)小數(shù)、分?jǐn)?shù)加減乘除法的計(jì)算方法解答．

解答 解：

2.4+2.36=4.76	4.5÷0.9=5	0.8×0.5=0.4	0÷0.99=0
4.02+$\frac{3}{5}$-0.02=4.6	$\frac{6}{7}$÷$\frac{9}{14}$=$\frac{4}{3}$	$\frac{2}{7}$-$\frac{1}{6}$=$\frac{5}{42}$	3.5×$\frac{4}{5}$=2.8

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．
