Answer 1

Respuesta:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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