答案:
解析:
这些题目主要考查分数的四则运算,包括分数的加法、减法、乘法、除法以及与小数的混合运算。
答案:
$\frac{2}{7} ÷ \frac{3}{7} = \frac{2}{3}$;
$\frac{1}{2} + \frac{3}{4} = \frac{5}{4}$;
$0 × \frac{8}{11} = 0$;
$\frac{2}{3} ÷ \frac{3}{5} = \frac{10}{9}$;
$\frac{5}{6} × \frac{4}{5} = \frac{2}{3}$;
$\frac{3}{4} ÷ \frac{1}{4} = 3$;
$\frac{5}{6} × \frac{7}{15} = \frac{7}{18}$;
$\frac{7}{10} ÷ \frac{2}{5} = \frac{7}{4}$;
$\frac{4}{7} - \frac{2}{21} = \frac{10}{21}$;
$6 ÷ \frac{1}{2} = 12$;
$\frac{15}{8} ÷ 5 = \frac{3}{8}$;
$\frac{7}{9} ÷ \frac{7}{9} = 1$;
$16 ÷ \frac{2}{7} = 56$;
$\frac{2}{7} × \frac{5}{2} × \frac{7}{5} = 1$;
$\frac{4}{7} ÷ \frac{5}{7} = \frac{4}{5}$;
$\frac{1}{2} - \frac{1}{5} = \frac{3}{10}$;
$\frac{4}{9} × \frac{3}{11} = \frac{4}{33}$;
$\frac{1}{6} ÷ \frac{1}{2} = \frac{1}{3}$;
$\frac{2}{9} × 0.63 = 0.14$;
$\frac{1}{2} ÷ \frac{2}{3} = \frac{3}{4}$;
$\frac{3}{4} ÷ 20 = \frac{3}{80}$;
$\frac{7}{8} - \frac{1}{4} = \frac{5}{8}$;
$3.2 × \frac{3}{8} = 1.2$;
$\frac{5}{18} × \frac{3}{5} + \frac{5}{6} = 1$。
