Question

alguien me ayuda con ejemplos

Answer 1

Respuesta:

$\frac{15}{4}-\frac{7}{2}=\frac{15-14}{4}= \frac{1}{4}$

$\frac{17}{5}-\frac{12}{8} =\frac{136-60}{40} =\frac{76}{40}$

$\frac{16}{10} -\frac{10}{3} =\frac{48-100}{30} =\frac{-52}{30}$

$\frac{17}{6} -\frac{5}{7} =\frac{119-30}{42} =\frac{89}{42}$

$\frac{20}{7}- \frac{3}{5}=\frac{100-31}{35}=\frac{69}{35}$

$\frac{8}{12} +\frac{6}{12}=\frac{14}{12}$

$\frac{45}{135} +\frac{20}{135} =\frac{65}{135}$

$\frac{18}{50} +\frac{32}{50}=\frac{50}{50}$

$\frac{35}{53} +\frac{15}{53} =\frac{50}{53}$

$\frac{28}{32} +\frac{14}{32} =\frac{42}{32}$

$\frac{5}{8} +\frac{3}{8} =\frac{8}{8}$
