Answer 1

Respuesta:

$a) - 6 \times ( - 4 + 16) \div 2 = - 6 \times 12 \div 2 = - 72 \div 2 = - 36$

$b)( - 12 + 20) \times [20 \div ( - 2)] = 8 \times ( - 10) = - 80$

$c)( \frac{3}{4} + \frac{5}{ 12} ) \div ( - 4) = ( \frac{9}{12} + \frac{5}{12} ) \div ( - 4) = \frac{14}{12} \div ( - 4) = \frac{14}{12} \times ( - \frac{1}{4} ) = - \frac{7}{24}$

$d)2 \frac{1}{2} \times \frac{1}{6} - 1.5 = \frac{5}{2} \times \frac{1}{6} - \frac{3}{2} = \frac{5}{12} - \frac{3}{2} = \frac{5}{12} - \frac{18}{12} = - \frac{13}{12}$
