Question

resolva: (1/2)+(-14/5)-(+1,2)​

Answer 1

Resposta:

(1/2) + (-14/5) - (+1,2)

$( \frac{1}{2} ) + ( - \frac{14}{5} ) - ( + 1.2)$

$( \frac{1}{2} ) + ( - \frac{14}{5} ) - ( + \frac{12}{10})$

$= \frac{1}{2(5)} - \frac{14}{5(2)} - \frac{12}{10(1)}$

$= \frac{5}{10} - \frac{28}{10} - \frac{12}{10}$

$= \frac{5 - 28 - 12}{10} = - \frac{35 }{10}$
