\(\frac{3\times (-10)}{8}-\frac{2}{-10}\\ =\frac{-30}{8}+\frac{2}{10}\\ =\frac{-15}{4}+\frac{2}{10}\\ =\frac{-15}{4}\times \frac{5}{5}+\frac{2}{10}\times \frac{2}{2}\\ =\frac{-75}{20}+\frac{4}{20}\\ =\frac{-75+4}{20}\\ =\frac{-71}{20}\\ =-3\frac{11}{20}\\\)
check with the calc :)
3(-10)/8-2/(-10) = -3.55
