Question

12．直接寫(xiě)得數(shù)．
$\frac{3}{4}$×$\frac{1}{2}$=
$\frac{6}{7}$÷2=
$\frac{6}{7}$×$\frac{1}{6}$=
68÷10%=
$\frac{5}{8}$×72%=

Answer 1

分析 根據(jù)分?jǐn)?shù)和百分?jǐn)?shù)加減乘除法運(yùn)算的計(jì)算法則計(jì)算即可求解．

解答 解：$\frac{3}{4}$×$\frac{1}{2}$=$\frac{3}{8}$
$\frac{6}{7}$÷2=$\frac{3}{7}$
$\frac{6}{7}$×$\frac{1}{6}$=$\frac{1}{7}$
68÷10%=680
$\frac{5}{8}$×72%=0.45

點(diǎn)評(píng) 考查了分?jǐn)?shù)和百分?jǐn)?shù)加減乘除法運(yùn)算，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
