1. 直接写出得数。
$1 - \frac{3}{4} =$ $\frac{1}{2} - \frac{1}{3} =$ $\frac{1}{9} + \frac{5}{9} =$ $\frac{7}{20} + \frac{3}{20} =$
$\frac{7}{8} + \frac{1}{8} =$ $\frac{13}{10} + \frac{7}{10} =$ $\frac{7}{9} - \frac{1}{3} =$ $\frac{2}{7} + \frac{1}{5} =$
$\frac{3}{11} + \frac{6}{11} =$ $\frac{10}{19} + \frac{9}{19} =$ $\frac{11}{16} - \frac{5}{16} =$ $\frac{18}{19} - \frac{9}{19} =$
$\frac{3}{8} - \frac{1}{5} =$ $1 - \frac{11}{24} =$ $\frac{1}{6} + \frac{13}{6} =$ $\frac{6}{17} + \frac{4}{17} =$
$\frac{8}{9} + \frac{2}{9} =$ $\frac{14}{11} - \frac{3}{11} =$ $\frac{17}{12} - \frac{5}{12} =$ $\frac{14}{15} - \frac{4}{15} =$

答案： $\frac{1}{4}$@@$\frac{1}{6}$@@$\frac{2}{3}$@@$\frac{1}{2}$@@1@@2@@$\frac{4}{9}$@@$\frac{17}{35}$@@$\frac{9}{11}$@@1@@$\frac{3}{8}$@@$\frac{9}{19}$@@$\frac{7}{40}$@@$\frac{13}{24}$@@$\frac{7}{3}$@@$\frac{10}{17}$@@$\frac{10}{9}$@@1@@1@@$\frac{2}{3}$

2. 在〇里填上“＞”“＜”或“＝”。
$\frac{5}{6} - \frac{1}{6}〇\frac{4}{13}$ $\frac{4}{5} - \frac{2}{5}〇\frac{9}{10} - \frac{4}{10}$ $\frac{5}{12} - \frac{1}{12}〇\frac{6}{7} - \frac{2}{7}$
$\frac{1}{3} - \frac{1}{4}〇\frac{1}{6}$ $\frac{4}{7} + \frac{2}{21}〇1 - \frac{1}{2}$ $\frac{2}{9} - \frac{1}{18}〇\frac{2}{3} - \frac{1}{6}$

答案： ＞@@＜@@＜@@＜@@＞@@＜

3. 计算下面各题。
$\frac{7}{10} - \frac{4}{15}$ $\frac{5}{6} + \frac{2}{5}$ $\frac{13}{18} - \frac{4}{9}$
$\frac{7}{12} + \frac{5}{18}$ $\frac{19}{24} + \frac{3}{4}$ $\frac{2}{3} - \frac{4}{11}$

答案： $\frac{13}{30}$@@$\frac{37}{30}$@@$\frac{5}{18}$@@$\frac{31}{36}$@@$\frac{37}{24}$@@$\frac{10}{33}$
