Question

Ayudaaaaaa porfaaaaaaaaaa!!

Answer 1

PROBLEMA 1

$\frac{ \frac{3}{5} - \frac{2}{7} + ( \frac{4}{3} - \frac{5}{4} ) }{ \frac{2}{3} } \\ \frac{ \frac{11}{35} + \frac{1}{12} }{ \frac{2}{3} } \\ \frac{ \frac{167}{420} }{ \frac{2}{3} } \\ \frac{167}{280}$

PROBLEMA 2

$\frac{ \frac{3}{5} \times \frac{4}{5} - \frac{2}{8} + ( \frac{2}{3} - \frac{3}{4}) }{ \frac{1}{4} } \\ \frac{ \frac{12}{25} - \frac{2}{8} - \frac{1}{12} }{ \frac{1}{4} } \\ \frac{ \frac{11}{75} }{ \frac{1}{4} } \\ \frac{44}{75}$
