一、算法。
$\frac {7}{10}+\frac {1}{4}=$$\frac{19}{20}$
$\frac {5}{9}×\frac {4}{5}=$$\frac{4}{9}$
$\frac {5}{12}+\frac {1}{3}=$$\frac{3}{4}$
$\frac {9}{4}×\frac {10}{27}=$$\frac{5}{6}$
$2÷\frac {4}{5}=$$\frac{5}{2}$
$\frac {4}{5}×\frac {6}{7}=$$\frac{24}{35}$
$\frac {5}{6}÷\frac {5}{9}=$$\frac{3}{2}$
$26×\frac {1}{13}=$2
$\frac {5}{17}÷\frac {5}{51}=$3
$\frac {5}{12}-\frac {1}{3}=$$\frac{1}{12}$
$\frac {5}{8}÷\frac {3}{2}=$$\frac{5}{12}$
$\frac {3}{5}+\frac {1}{10}=$$\frac{7}{10}$
$\frac {7}{12}×\frac {3}{14}=$$\frac{1}{8}$
$\frac {1}{8}+\frac {9}{14}=$$\frac{43}{56}$
$\frac {10}{21}×\frac {14}{25}=$$\frac{4}{15}$
$\frac {15}{16}×\frac {12}{25}=$$\frac{9}{20}$
$\frac {2}{5}÷10=$$\frac{1}{25}$
$\frac {5}{6}+\frac {1}{2}=$$\frac{4}{3}$
$2-\frac {2}{5}=$$1\frac{3}{5}$
$\frac {7}{15}×\frac {10}{21}=$$\frac{2}{9}$
$\frac {7}{18}÷\frac {5}{9}=$$\frac{7}{10}$
$\frac {8}{9}×\frac {3}{2}=$$\frac{4}{3}$
$\frac {8}{27}÷\frac {2}{9}=$$\frac{4}{3}$
$\frac {8}{3}×\frac {9}{4}=$6
