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
