一、直接写出得数。（共 32 分）
$ \frac{5}{8} + \frac{1}{4} = $$ $$ \frac{1}{6} - \frac{1}{12} = $$ $$ \frac{2}{3} + \frac{3}{2} = $$ $$ \frac{9}{10} × \frac{8}{9} × 0 = $
$ 1 - \frac{5}{7} = $$ $$ \frac{11}{2} + \frac{5}{4} = $$ $$ \frac{5}{6} + \frac{7}{12} = $$ $$ 60 × \frac{4}{15} × \frac{1}{4} = $
$ 28 × \frac{2}{21} = $$ $$ \frac{13}{24} × 60 = $$ $$ 48 × \frac{7}{36} = $$ $$ \frac{8}{3} × 6 × \frac{11}{8} = $
$ 16 × \frac{5}{24} = $$ $$ 15 × \frac{59}{60} = $$ $$ 100 × \frac{17}{20} = $$ $$ \frac{5}{6} × \frac{7}{5} × 6 = $
$ \frac{7}{8} × \frac{5}{7} = $$ $$ \frac{11}{5} × \frac{10}{11} = $$ $$ \frac{5}{12} × \frac{2}{3} = $$ $$ \frac{1}{15} × \frac{3}{5} × \frac{2}{5} = $
$ \frac{13}{8} × \frac{4}{39} = $$ $$ \frac{3}{5} × \frac{5}{6} = $$ $$ \frac{4}{7} × \frac{49}{30} = $$ $$ \frac{2}{7} × \frac{5}{11} × \frac{7}{8} = $
$ \frac{2}{5} × \frac{1}{6} = $$ $$ \frac{5}{13} × \frac{26}{15} = $$ $$ \frac{18}{35} × \frac{14}{27} = $$ $$ \frac{4}{5} × \frac{3}{8} × \frac{5}{6} = $
$ \frac{2}{3} × \frac{2}{3} = $$ $$ \frac{8}{5} × \frac{5}{8} = $$ $$ \frac{13}{16} × \frac{8}{13} = $$ $$ \frac{2}{9} × \frac{3}{4} × \frac{5}{3} = $

二、将互为倒数的两个数连起来。（共 12 分）
$ \frac{5}{6} 1 1.25 \frac{2}{17} \frac{19}{14} 1.80.8 \frac{6}{5} \frac{8}{8} \frac{5}{9} \frac{14}{19} 8.5$

三、在$$ ◯ $$里填“$$ ＞ $$”“$$ ＜ $$”或“$$ = $$”。（共 12 分）
$ \frac{2}{3} × \frac{4}{5} ◯ \frac{2}{3} $$ $$ \frac{2}{3} × \frac{3}{2} ◯ 5 × \frac{1}{5} $$ $$ 2 × \frac{1}{2} ◯ 1 × \frac{1}{2} $
$ \frac{3}{10} × \frac{8}{7} ◯ \frac{8}{7} $$ $$ \frac{8}{11} × 1 ◯ \frac{8}{11} × \frac{11}{8} $$ $$ \frac{4}{9} × \frac{3}{4} ◯ \frac{4}{9} × \frac{4}{3} $
