Question

15．直接寫得數(shù)．

0.35+5=	1-（$\frac{1}{5}$+$\frac{4}{5}$）=	$\frac{1}{11}$×12.1=	1.01-0.1=
10-0.99=	$\frac{13}{27}$×8+$\frac{13}{27}$=	1÷0.1×0.1=	0.25×0.4=
$\frac{1}{6}$+$\frac{1}{6}$÷$\frac{1}{6}$=	$\frac{5}{9}$×$\frac{1}{5}$÷$\frac{5}{9}$=	a-a×$\frac{3}{4}$=	$\frac{1}{8}$÷$\frac{1}{8}$×$\frac{1}{8}$=

Answer 1

分析 根據(jù)小數(shù)加減乘除法的計(jì)算法則及分?jǐn)?shù)加減乘除法的計(jì)算法則進(jìn)行計(jì)算．

解答

解：0.35+5=5.35	1-（$\frac{1}{5}$+$\frac{4}{5}$）=0	$\frac{1}{11}$×12.1=1.1	1.01-0.1=0.91
10-0.99=9.01	$\frac{13}{27}$×8+$\frac{13}{27}$=$4\frac{1}{3}$	1÷0.1×0.1=1	0.25×0.4=0.1
$\frac{1}{6}$+$\frac{1}{6}$÷$\frac{1}{6}$=$1\frac{1}{6}$	$\frac{5}{9}$×$\frac{1}{5}$÷$\frac{5}{9}$=$\frac{1}{5}$	a-a×$\frac{3}{4}$=$\frac{a}{4}$	$\frac{1}{8}$÷$\frac{1}{8}$×$\frac{1}{8}$=$\frac{1}{8}$

點(diǎn)評(píng) 本組題綜合考查了學(xué)生的基本的計(jì)算能力．
