Question

7．直接写得数：

2-0.5=	2.7+3.6=	5.6×$\frac{7}{8}$=	$\frac{4}{5}$×$\frac{3}{4}$=	$\frac{1}{3}$+$\frac{1}{4}$=
$\frac{1}{8}$+0.625=	9.96-0.98=	6-2$\frac{3}{4}$=	$\frac{4}{5}$×$\frac{2}{3}$÷$\frac{4}{5}$×$\frac{2}{3}$=	$\frac{5}{6}$×18=

Answer 1

分析 根据小数、分数加减乘除法的计算方法进行解答即可．

解答 解：

2-0.5=1.5	2.7+3.6=6.3	5.6×$\frac{7}{8}$=4.9	$\frac{4}{5}$×$\frac{3}{4}$=$\frac{3}{5}$	$\frac{1}{3}$+$\frac{1}{4}$=$\frac{7}{12}$
$\frac{1}{8}$+0.625=0.75	9.96-0.98=8.98	6-2$\frac{3}{4}$=3$\frac{1}{4}$	$\frac{4}{5}$×$\frac{2}{3}$÷$\frac{4}{5}$×$\frac{2}{3}$=$\frac{4}{9}$	$\frac{5}{6}$×18=15

点评 此题考查了小数、分数加减乘除法的口算能力．
