Answer 1

a ) $\frac{-5}{3} +1 = \frac{-5+3}{3} = \frac{-2}{3}$

b) $\frac{4}{3}+ \frac{-3}{4}= \frac{16-9}{12}= \frac{7}{12}$

f ) $\frac{11}{6}- \frac{7}{5}= \frac{55-42}{30}= \frac{13}{30}$

g) -$\frac{3}{4}. \frac{5}{6}= \frac{-15}{24}= \frac{-5}{8}$

k) $\frac{-45}{12}$÷$\frac{5}{18}= \frac{-810}{60}= \frac{-27}{2}$

l) (-$\frac{1}{4}).2 +  \frac{5}{6}. \frac{3}{2}- \frac{5}{3}$

$\frac{-2}{4}+ \frac{15}{12}- \frac{5}{3}$

$\frac{-1}{2}+ \frac{5}{4}- \frac{5}{3}= \frac{-6+15-20}{12}= \frac{-11}{12}$
