Question

-11/18+(-7/108)+(-14/3)+(-5/36)

Answer 1

$- \frac{11}{18}+(- \frac{7}{108})+(- \frac{14}{3})+(- \frac{5}{36})=$

{amplificam prima factie cu 6, a doua o lasam asa, a treia cu 36 si ultima cu 3}

$= - \frac{66}{108}+(- \frac{7}{108})+(- \frac{504}{108})+(-\frac{15}{108})=$

$=- \frac{66}{108}- \frac{7}{108} - \frac{504}{108} -\frac{15}{108})=$

$=\frac{-66-7-504-15}{108}=$

$=\frac{-592}{108}=$

$=\frac{-148}{27}=$

$=\boxed{-5\frac{13}{27}}$
