Step-by-step explanation:

first we take first and third 4/7+(-5/14)

lcm for 7,14 is 14

4*2/(7*2)+(-5)/14=(8-5)/14=3/14--------1)

next we take second and fourth terms

-5/13+3/26

lcm for 13,26 is 26

=-5*2/(13*2)+3/26=(-10+3)/26=(-7/26)------2)

add 1) +2)

3/14 - 7/26

lcm for 14,26 is 182

=(3*13)/182 - (7*7) /182

=(39-49) /182

=(-10) /182=(-5) /91
