ayuda porfavor

Answer 1

$(3/8+7/6)-(4/12-3/24)=(\frac{9+28}{24})-(\frac{8-3}{24} ) = \frac{37}{24} - \frac{5}{24} = \frac{32}{24} = \frac{4}{3}$ 

-5/3÷2/7=$- \frac{5}{3} * \frac{7}{2} = -\frac{35}{6}$

3/8+2-1/6=$\frac{9+48-4}{24}= \frac{53}{24}$

4/17*(-3/5)÷(2/-6)=$-\frac{12}{85}/( \frac{2}{-6} )= -\frac{12}{85} *(- \frac{6}{12} )= \frac{36}{85}$

(-2/3)÷(-4/7)=$(- \frac{2}{3} )*(- \frac{7}{4}) = \frac{7}{6}$
