Answer 1

a)2/3+5/3= 7/3
b)11/19+3/19=14/19
c)10/11-5/11+7/11=12/11

Answer 2

$a) \\ \frac{2}{3} + \frac{5}{3} => \frac{7}{3} \\ \\ \\ b) \\ \frac{11}{19} + \frac{3}{18} => \frac{14}{19} \\ \\ \\ c) \\ \frac{10}{11} - \frac{5}{11} + \frac{7}{11} \\ \\ \\ \frac{5}{11} +\frac{7}{11} => \frac{12}{11}$
