2) 14/5

3) 47/14

4)27/56

5) 10/7

6) 23/14

Step-by-step explanation:

We will apply the Least Common Multiple (LCM). because, each exercise has fractions without a common a denominator

$\frac{3}{4} +\frac{2}{5} = \frac{15+8}{20} =\frac{23}{20}\\\\1 +\frac{9}{5} = \frac{5+9}{5} =\frac{14}{5}\\\\\frac{13}{7} +\frac{3}{2} = \frac{26+21}{14} =\frac{47}{14}\\\\\frac{5}{8} -\frac{1}{7} = \frac{35-8}{56} =\frac{27}{56}\\\\1 +\frac{3}{7} = \frac{7+3}{7} =\frac{10}{7}\\\\\frac{1}{7} +\frac{3}{2} = \frac{2+21}{14} =\frac{23}{14}$
