Question

б) - (1/8+5/12)+(-1 1/3+1,5)
Помогите пожалуйста

Answer 1

$-\bigg(\dfrac{1}{8}+\dfrac{5}{12}\bigg)+\bigg(-1\dfrac{1}{3}+1,5\bigg)=-0,375$

$1) \: \: \dfrac{1}{8}+\dfrac{5}{12}=\dfrac{3}{24}+\dfrac{10}{24}=\dfrac{13}{24}$

$2) \: \: -1\dfrac{1}{3}+1,5=-\dfrac{4}{3}+\dfrac{3}{2}=-\dfrac{8}{6}+\dfrac{9}{6}=\dfrac{1}{6}$

$3) \: \: -\dfrac{13}{24}+\dfrac{1}{6}=-\dfrac{13}{24}+\dfrac{4}{24}=-\dfrac{9}{24}=-\dfrac{3}{8}=-0,375$
