hope it is helpful for you

Answer 2

to find the greatest no. among all, first we need to take lcm of denominators, i.e 28,7,14 and 24.   
L.C.M = 168

Now, a) -11/28 = -66/168
          b) -5/7 =  -120/168
          c) -9/14 = -108/168
          d) -29/24 = -203/168

Clearly, Option A or -11/28 is the greatest of all
