Question

fie numarul×=3/8×[-1/4-(1/24-7/36):(-7/6)] .ajutorrrr​

Answer 1

$x = \frac{3}{8} \times ( - \frac{1}{4} - ( \frac{1}{24} - \frac{7}{36} ) \div ( - \frac{7}{6} )) \\ \\ x = \frac{3}{8} \times ( - \frac{1}{4} - ( \frac{3 - 14}{72} ) \times ( - \frac{6}{7} )) \\ \\ x = \frac{3}{8} \times ( - \frac{1}{4} - ( - \frac{11}{72} ) \times ( - \frac{6}{7} )) \\ \\ x = \frac{3}{8} \times ( - \frac{1}{4} - ( - \frac{11}{12} \times ( - \frac{1}{7} )) \\ \\ x = \frac{3}{8} \times ( - \frac{1}{4} - \frac{11}{84} ) \\ \\ x = \frac{3}{8} \times ( - \frac{21}{84} - \frac{11}{84} ) \\ \\ x = \frac{3}{8} \times ( - \frac{32}{84} ) \\ \\ x = \frac{1}{1} \times ( - \frac{4}{28} ) \\ \\ x = - \frac{4}{28} \\ \\ x = - - \frac{1}{7}$
