alguien que me ayude daré coronita​

Answer 1

Respuesta:

1.- $\frac{6}{10} +\frac{8}{10} +\frac{14}{10} =\frac{28}{10}$

2.-$\frac{9}{7} -\frac{12}{4} =\frac{36-84}{28} =\frac{-48}{28} =-\frac{12}{7}$

3.-$\frac{8}{5} +\frac{3}{4} +\frac{7}{10}= \frac{32+15+14}{20}=\frac{61}{20}$

4.-$(-\frac{6}{4} )(\frac{8}{7} )(-\frac{3}{2}) =\frac{6.8.3}{4.7.2}= \frac{144}{56} =\frac{18}{7}$

5.-$\frac{-\frac{15}{9} }{-\frac{3}{4} } =\frac{\frac{5}{3} }{\frac{3}{4} } =\frac{5.4}{3.3} =\frac{20}{9}$

6.-$\frac{9}{8}:\frac{6}{7} =\frac{9}{8} *\frac{7}{6} =\frac{9*7}{8*6} =\frac{63}{48} =\frac{21}{16}$

7.-$\frac{10}{15}-(-\frac{4}{6})=\frac{2}{3}+\frac{2}{3} =\frac{4}{3}$
