Una ayudita Plisss porfis ​

Answer 1

Explicación paso a paso:

$\frac{4}{5} \times ( \frac{3}{2} + \frac{1}{3} ) \\ \\ \frac{4}{5} \times ( \frac{9 + 2}{6} ) = \frac{4}{5} \times \frac{11}{6} = \frac{44}{30} \\ smplifcamos \: y \: queda \\ \\ \frac{22}{15}$

$- \frac{2}{7} + ( \frac{1}{3} \div \frac{6}{5} ) \\ \\ - \frac{2}{7} + \frac{5}{18} = \frac{ - 36 +35 }{126} = - \frac{1}{126}$

$2 \times 0.25 \times \frac{3}{4} + 0.5 \\ \\ 0.375+ 0.5 = 0.875$

$\sqrt{6.25} \times \frac{1}{5} + ( \sqrt{ - 0.81} \\ \\ 2.5 \times \frac{1}{5} + ( - 0.9) \\ \\ 0.5 - 0.9 = - 0.4$
