Answer 2

Respuestas:

$\frac{1}{5}+\frac{4}{3}+\frac{1}{2} = \frac{6}{30}+\frac{40}{30}+\frac{15}{30} = \frac{61}{30}$

$\frac{2}{3} + \frac{1}{9} + \frac{3}{5} = \frac{30}{45} + \frac{5}{45} + \frac{27}{45} = \frac{62}{45}$

$\frac{4}{7} + \frac{2}{4} + \frac{3}{5} = \frac{80}{140} + \frac{70}{140} + \frac{84}{140} = \frac{234}{140}$

$\frac{3}{2}+ \frac{1}{5}+ \frac{1}{10} =\frac{15}{10} +\frac{2}{10}+ \frac{1}{10} =\frac{18}{10}$

$\frac{3}{8}+ \frac{1}{4}+ \frac{3}{16} =\frac{6}{16} +\frac{4}{16}+ \frac{3}{16}= \frac{13}{16}$

$\frac{4}{5} -\frac{1}{7} =\frac{28}{35} - \frac{5}{35} =\frac{21}{35}$

$\frac{2}{3} -\frac{4}{7} =\frac{14}{21}- \frac{12}{21}= \frac{2}{21}$

$\frac{3}{10}- \frac{1}{12} =\frac{36}{120} -\frac{10}{120}= \frac{26}{120}$

$\frac{9}{15} -\frac{3}{8} =\frac{72}{120} -\frac{45}{120}= \frac{27}{120}$
