Answer 1

Answer:

-14/5

Step-by-step explanation:

$=> 2/5 + 3/7 + (-6)/5 + (-13)/7\\=> [(2 + -6)/5] + [(3 + -13)/7]\\=>(-4/5) + (-10/7)\\taking-LCM-as-5*7 = 35-\\>> -4/5 = -4*7/5*7 = -28/35\\>> -10/7 = -10 * 5/7*5 = -70/35\\=> (-4/5) + (-10/7) = (-28/35) + (-70/35)\\=> (-28)+(-70)/35 = -(28+70)/35\\=> -98/35\\=> -14/5 (by-dividing-7-from-each)$
