Question

alguien que sepa de mates me ayude pls

Answer 1

Explicación paso a paso:

el primero

$(2 + \frac{1}{3} ) \div \frac{5}{6} = \frac{7}{3} \div \frac{5}{6} = \frac{42}{15} = \frac{14}{5}$

el segundo

$( \frac{3}{6} - \frac{1}{3} ) \div - \frac{7}{15} = \frac{1}{6} \div - \frac{7}{15} = - \frac{15}{42} = - \frac{5}{14}$

el tercero

$( \frac{1}{2} + \frac{3}{4} ( \frac{2}{5} )) \div ( - \frac{1}{6} ) = ( \frac{1}{2} + \frac{6}{20}) \div ( - \frac{1}{6} ) = \frac{4}{5} \div ( - \frac{1}{6} ) = - \frac{24}{5}$

el cuarto

$( \frac{1}{4} + \frac{3}{2} ( \frac{4}{5} )) \div ( \frac{3}{4} ( - \frac{1}{2} ) - \frac{1}{6} ) =$

$( \frac{1}{4} + \frac{12}{10} ) \div ( - \frac{3}{8} - \frac{1}{6} ) = \frac{29}{20} \div ( - \frac{13}{24} ) = - \frac{174}{65}$
