e) $\frac{-3}{5}$ + $\frac{1}{4}$ - $\frac{-3}{10}$
= $\frac{-12}{20}$ + $\frac{5}{20}$ - $\frac{-3}{10}$
= $\frac{-7}{20}$ - $\frac{-3}{10}$
= $\frac{-7}{20}$ - $\frac{-6}{20}$
= $\frac{-1}{20}$
a) $\frac{1}{5}$ - $\frac{1}{2}$ + $\frac{1}{3}$
= $\frac{6}{30}$ - $\frac{15}{30}$ +$\frac{10}{30}$
= $\frac{-9}{30}$ + $\frac{10}{30}$
= $\frac{1}{30}$
b) 3 - $\frac{1}{2}$ + $\frac{-1}{5}$
= $\frac{6}{2}$ - $\frac{1}{2}$ + $\frac{-1}{5}$
= $\frac{5}{2}$ + $\frac{-1}{5}$
= $\frac{25}{10}$ + $\frac{-2}{10}$
= $\frac{23}{10}$
c) 4 + $\frac{1}{3}$ - $\frac{1}{5}$
= $\frac{12}{3}$ + $\frac{1}{3}$ - $\frac{1}{5}$
= $\frac{13}{3}$ - $\frac{1}{5}$
= $\frac{65}{15}$ - $\frac{3}{15}$
= $\frac{62}{15}$
d) $\frac{5}{4}$ - $\frac{1}{3}$ - $\frac{-3}{8}$
= $\frac{15}{12}$ - $\frac{4}{12}$ - $\frac{-3}{8}$
= $\frac{11}{12}$ - $\frac{-3}{8}$
= $\frac{88}{96}$ - $\frac{-36}{96}$
= $\frac{31}{24}$
