Question

-{2/3+[1/5-(2/15+3/4)-5/4]+1

Answer 1

Respuesta:

$=-\frac{8}{5}$

Explicación paso a paso:

=$-\frac{2}{3}+\left(\frac{1}{5}-\left(\frac{2}{15}+\frac{3}{4}\right)-\frac{5}{4}\right)+1$

=$-\frac{2}{3}+\frac{1}{5}-\left(\frac{2}{15}+\frac{3}{4}\right)-\frac{5}{4}+1$

$=-\frac{2}{3}+\frac{1}{5}-\frac{53}{60}-\frac{5}{4}+1$

$=\frac{1}{1}-\frac{2}{3}+\frac{1}{5}-\frac{53}{60}-\frac{5}{4}$

$=\frac{60}{60}-\frac{40}{60}+\frac{12}{60}-\frac{53}{60}-\frac{75}{60}$

$=\frac{60-40+12-53-75}{60}$

$=\frac{-96}{60}$

$=-\frac{8}{5}$
