Question

18．直接寫出的數(shù)．

906+94=	0.7×10=	0.8+9.2=	700-388=	1672÷8=
$8.6-1\frac{3}{5}$=	$10-2\frac{6}{7}$=	$5\frac{3}{4}×0$=	$\frac{1}{6}×5.4$=	$\frac{5}{12}×\frac{6}{25}$=

Answer 1

分析 根據(jù)整數(shù)、小數(shù)和分?jǐn)?shù)四則運(yùn)算的計(jì)算法則進(jìn)行計(jì)算即可．

解答

解：906+94=1000	0.7×10=7	0.8+9.2=10	700-388=312	1672÷8=209
$8.6-1\frac{3}{5}$=7	$10-2\frac{6}{7}$=7$\frac{1}{7}$	$5\frac{3}{4}×0$=0	$\frac{1}{6}×5.4$=0.9	$\frac{5}{12}×\frac{6}{25}$=$\frac{1}{10}$

點(diǎn)評 此題考查了整數(shù)、小數(shù)四則運(yùn)算的計(jì)算法則的運(yùn)用．
