Question

CALCULA
A) 5X1/10-(3/5-2/5)X2/3 B) 2/3X15/4-(1/6÷1/12+1/8)

Answer 1

$A) 5* \frac{1}{10} - ( \frac{3}{5}- \frac{2}{5})* \frac{2}{3}= \qquad primero \ resolvemos \ el \ parentesis \\ \\ 5* \frac{1}{10} - ( \frac{1}{5})* \frac{2}{3}= \\ \\ 5* \frac{1}{10} - \frac{1}{5}* \frac{2}{3}= \qquad segundo \ resolvemos \ las \ mulltiplicaciones \\ \\ \frac{1}{2} - \frac{2}{15}=\qquad tercero \ resolvemos \ la \ resta \\ \\ \frac{15}{30} - \frac{4}{30}= \boxed{ \frac{11}{30}}$

$B) \frac{2}{3} * \frac{15}{4}-( \frac{1}{6}: \frac{1}{12}+ \frac{1}{8})= \\ \\ \frac{2}{3} * \frac{15}{4}-( \frac{1*12}{6*1}+ \frac{1}{8})= \\ \\ \frac{2}{3} * \frac{15}{4}-( 2+ \frac{1}{8})= \\ \\ \frac{2}{3} * \frac{15}{4}-( \frac{16}{8}+ \frac{1}{8})= \\ \\ \frac{5}{2} - \frac{17}{8}= \frac{4*5-17}{8}= \frac{20-17}{8}= \boxed{ \frac{3}{8}}$

Espero que te sirva, salu2!!!!
