Question

15．直接寫(xiě)出得數(shù)．

7÷3=	$\frac{1}{3}$×2=	$\frac{3}{4}$×$\frac{2}{3}$=	$\frac{5}{6}$×$\frac{2}{5}$=
2×$\frac{2}{3}$=	4÷$\frac{1}{4}$=	$\frac{4}{9}$÷$\frac{2}{3}$=	$\frac{5}{6}$+$\frac{3}{8}$=

Answer 1

分析 根據(jù)整數(shù)除法和分?jǐn)?shù)加減乘除法的計(jì)算方法解答．

解答 解：

7÷3=$\frac{7}{3}$	$\frac{1}{3}$×2=$\frac{2}{3}$	$\frac{3}{4}$×$\frac{2}{3}$=$\frac{1}{2}$	$\frac{5}{6}$×$\frac{2}{5}$=$\frac{1}{3}$
2×$\frac{2}{3}$=$\frac{4}{3}$	4÷$\frac{1}{4}$=16	$\frac{4}{9}$÷$\frac{2}{3}$=$\frac{2}{3}$	$\frac{5}{6}$+$\frac{3}{8}$=$\frac{29}{24}$

點(diǎn)評(píng) 直接寫(xiě)得數(shù)時(shí)，注意數(shù)據(jù)特點(diǎn)和運(yùn)算符號(hào)，細(xì)心解答即可．
