a) 5,15-(-3[tex]\frac{3}{5}[/tex]) = [tex]5\frac{15}{100} +3\frac{60}{100} = 8\frac{75}{100} = 8\frac{3}{4}[/tex]
b)[tex]-5\frac{4}{5} - 3,1=-5\frac{8}{10} - 3\frac{1}{10} =-8\frac{9}{10}[/tex]
c) [tex]-6\frac{4}{7} +4,5=-6\frac{4}{7} +4\frac{1}{2} =-6\frac{8}{14} +4\frac{7}{14}=-2\frac{1}{14}[/tex]
d)[tex]-5,6-(-2\frac{3}{8})=-5\frac{3}{5} +2\frac{3}{8} =-5\frac{24}{40} +2\frac{15}{40}=3\frac{9}{40}[/tex]
Pozdro ;)
