2) 14/5

3) 47/14

4)27/56

5) 10/7

6) 23/14

Explanation:

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

`(3)/(4) +(2)/(5) = (15+8)/(20) =(23)/(20)\\\\1 +(9)/(5) = (5+9)/(5) =(14)/(5)\\\\(13)/(7) +(3)/(2) = (26+21)/(14) =(47)/(14)\\\\(5)/(8) -(1)/(7) = (35-8)/(56) =(27)/(56)\\\\1 +(3)/(7) = (7+3)/(7) =(10)/(7)\\\\(1)/(7) +(3)/(2) = (2+21)/(14) =(23)/(14)`
