1. 直接写出得数。
$\frac{1}{4}+\frac{3}{4}=$ $1-\frac{2}{7}=$ $\frac{1}{8}+\frac{5}{8}=$ $2-\frac{3}{4}-\frac{1}{4}=$
$\frac{5}{8}-\frac{3}{8}=$ $\frac{2}{5}+\frac{2}{5}=$ $\frac{5}{6}-\frac{1}{6}=$ $\frac{7}{11}+\frac{2}{33}+\frac{4}{11}=$
$\frac{2}{3}+\frac{5}{3}=$ $\frac{7}{10}-\frac{7}{10}=$ $\frac{8}{11}+\frac{4}{11}=$ $\frac{5}{12}-\frac{4}{13}+\frac{7}{12}=$
$\frac{7}{12}-\frac{5}{12}=$ $\frac{3}{4}+\frac{5}{4}=$ $\frac{8}{9}-\frac{7}{9}=$ $\frac{17}{13}+\frac{1}{5}-\frac{4}{13}=$
$\frac{9}{10}-\frac{3}{10}=$ $\frac{7}{8}+\frac{3}{8}=$ $\frac{7}{9}+\frac{2}{9}=$ $\frac{1}{2}+\frac{9}{22}+\frac{1}{2}=$
$\frac{15}{13}-\frac{2}{13}=$ $\frac{3}{14}+\frac{5}{14}=$ $\frac{3}{8}+\frac{9}{8}=$ $1-\frac{3}{5}+\frac{2}{5}=$
$\frac{6}{7}-\frac{2}{7}=$ $\frac{8}{15}-\frac{2}{15}=$ $1-\frac{9}{11}=$ $\frac{2}{9}+\frac{7}{9}-1=$
