Question

10．直接寫得數(shù)．

8×$\frac{6}{7}$=	0.125×$\frac{1}{8}$=	$\frac{4}{5}$×5÷5×$\frac{4}{5}$=	36×（$\frac{1}{3}$+$\frac{1}{4}$）=	$\frac{3}{4}$×20=
0.7÷1%=	$\frac{1}{5}$÷$\frac{1}{4}$=	1.25×$\frac{6}{25}$×8=	1÷$\frac{1}{3}$×3=	$\frac{1}{49}$：$\frac{1}{7}$=$\frac{1}{7}$

Answer 1

分析 根據(jù)分?jǐn)?shù)加法乘法除法、小數(shù)乘除法的計(jì)算方法進(jìn)行計(jì)算即可；
$\frac{4}{5}$×5÷5×$\frac{4}{5}$根據(jù)乘法交換律進(jìn)行計(jì)算即可和結(jié)合律進(jìn)行計(jì)算即可；
36×（$\frac{1}{3}$+$\frac{1}{4}$）根據(jù)乘法分配律進(jìn)行計(jì)算即可；
1.25×$\frac{6}{25}$×8根據(jù)乘法交換律進(jìn)行計(jì)算即可．

解答 解：

8×$\frac{6}{7}$=$\frac{48}{7}$	0.125×$\frac{1}{8}$=$\frac{1}{64}$	$\frac{4}{5}$×5÷5×$\frac{4}{5}$=$\frac{16}{25}$	36×（$\frac{1}{3}$+$\frac{1}{4}$）=21	$\frac{3}{4}$×20=15
0.7÷1%=70	$\frac{1}{5}$÷$\frac{1}{4}$=$\frac{4}{5}$	1.25×$\frac{6}{25}$×8=$\frac{12}{5}$	1÷$\frac{1}{3}$×3=9	$\frac{1}{49}$：$\frac{1}{7}$=$\frac{1}{7}$

點(diǎn)評(píng) 考查了分?jǐn)?shù)加法乘法除法、小數(shù)乘除法的口算能力，按照各自的計(jì)算方法進(jìn)行計(jì)算即可；靈活運(yùn)用運(yùn)算定律進(jìn)行計(jì)算即可．
