 \frac{3}{7}  +  \frac{1}{3}  =  \frac{9}{21}  +  \frac{7}{21}  =  \frac{16}{21}

 \frac{11}{15}  +  \frac{1}{6}  =  \frac{22}{30}  +  \frac{5}{30}  =  \frac{27}{30}  =  \frac{9}{10}

 \frac{1}{11}  +  \frac{5}{9}  =  \frac{9}{99}  +  \frac{55}{99}  =  \frac{64}{99}

 \frac{1}{8}  +  \frac{7}{15}  =  \frac{15}{120}  +  \frac{56}{120}  =  \frac{71}{120}

 \frac{5}{8}  -  \frac{1}{4}  =  \frac{5}{8}  -  \frac{2}{8}  =  \frac{3}{8}

 \frac{2}{3}  -  \frac{1}{5}  =  \frac{10}{15}  -  \frac{3}{15}  =  \frac{7}{15}

 \frac{3}{5}  -  \frac{4}{7}  =  \frac{21}{35}  -  \frac{20}{35}  =  \frac{1}{35}

 \frac{7}{8}  -  \frac{1}{3}  =  \frac{21}{24}  -  \frac{8}{24}  =  \frac{13}{24}

 \frac{3}{11}  \times  \frac{7}{8}  =  \frac{21}{88}

 \frac{7}{10}  \times  \frac{5}{6}  =  \frac{7}{12}

 \frac{9}{10}  \times  \frac{2}{3}  = \frac{18}{30}  =  \frac{18 \div 6}{30 \div 6}  =  \frac{3}{5}

 \frac{6}{13}  \times  \frac{1}{15}  =  \frac{2}{65}

 \frac{5}{7}  \div  \frac{1}{3}  =  \frac{5}{7}  \times 3 =  \frac{15}{7}

 \frac{1}{6}  \div  \frac{1}{8}  =  \frac{1}{6}  \times 8 =  \frac{4}{3}

 \frac{7}{8}  \div  \frac{1}{2}  =  \frac{7}{8}  \times 2 =  \frac{7}{4}

 \frac{3}{14}  \div  \frac{1}{8}  =  \frac{3}{14}  \times 8 =  \frac{12}{7}

 \frac{4}{21}  \times 63 = 12

 \frac{2}{5}  \times 105 = 42

 \frac{11}{12}  \times 72 = 66

 \frac{8}{25}  \times 50 = 16
