Answer 2

$0,5+(-frac{1}{4})=frac{1}{2}+(-frac{1}{4})=frac{1}{2}-frac{1}{4}=frac{2-1}{4}=frac{1}{4}=0,25$

 

$-frac{1}{3}+0,5=-frac{1}{3}+frac{1}{2}=frac{1}{2}-frac{1}{3}=frac{3-2}{6}=frac{1}{6}$

 

$-frac{5}{9}-(-frac{2}{3})=-frac{5}{9}+frac{2}{3}=frac{2}{3}-frac{5}{9}=frac{6-5}{9}=frac{1}{9}$

 

$-1frac{1}{3}-1frac{1}{6}=-frac{4}{3}-frac{7}{6}=-(frac{4}{3}+frac{7}{6})=-(frac{8+7}{6})=-frac{15}{6}=-frac{5}{2}=-2frac{1}{2}=-2,5$
