答案:
$\frac{11}{20}-\frac{3}{20}=$ $\frac{3}{7}+\frac{3}{7}=$ $\frac{4}{15}-\frac{3}{15}=$
$\frac{8}{15}+\frac{2}{15}=$ $\frac{9}{10}+\frac{1}{10}=$ $\frac{7}{13}-\frac{4}{13}=$
$\frac{5}{11}+\frac{3}{11}=$ $\frac{4}{7}+\frac{1}{7}=$ $\frac{2}{13}+\frac{10}{13}=$
$\frac{10}{11}+\frac{1}{11}=$ $\frac{3}{9}+\frac{4}{9}=$ $\frac{5}{12}-\frac{4}{12}=$
$\frac{8}{15}+\frac{2}{15}=$ $\frac{9}{10}+\frac{1}{10}=$ $\frac{7}{13}-\frac{4}{13}=$
$\frac{5}{11}+\frac{3}{11}=$ $\frac{4}{7}+\frac{1}{7}=$ $\frac{2}{13}+\frac{10}{13}=$
$\frac{10}{11}+\frac{1}{11}=$ $\frac{3}{9}+\frac{4}{9}=$ $\frac{5}{12}-\frac{4}{12}=$
答案:
( ) + $\frac{1}{11}$ = $\frac{4}{11}$ + $\frac{7}{11}$ $\frac{7}{9}-\frac{4}{9}=$( ) - $\frac{1}{9}$
