Answer 1

Respuesta:

$\frac{7}{12} - | \frac{13}{20} - ( \frac{1}{5} + \frac{8}{15} ) | - | \frac{17}{ 30} + ( \frac{1}{2} - \frac{23}{30} ) | \\ \frac{7}{12} - | \frac{13}{20} - ( \frac{3}{15} + \frac{8}{15}) | - | \frac{17}{30} + ( \frac{15}{30} - \frac{23}{30}) | \\ \frac{7}{12} - | \frac{13}{20} - \frac{11}{15} | - | \frac{17}{30} - \frac{8}{30} | \\ \frac{7}{12} - | \frac{195}{300} - \frac{220}{300} | - | \frac{9}{30} | \\ \frac{7}{12} - ( - \frac{25}{300} ) - \frac{9}{30}$

$\frac{175}{300} + \frac{25}{300} - \frac{90}{300} \\ \frac{200}{300} - \frac{90}{300} \\ \frac{110}{300} \\ \frac{11}{30}$
