your 1st Question is :-

  Q ) A motor bike runs 52\frac{1}{2} km using 1 liter of petrol. how much distance will it cover for 2\frac{3}{4} liter of petrol ?

Answer :-

       1 liter ----------------   52\frac{1}{2} = 52.5

       2\frac{3}{4} -------------------? km

         1 * ? = 52.5 * 2.75

         ? = 144.375

so it will requare 144.375 km

your 2nd Question:-

  Q) a bucket contains 34\frac{1}{2} liters of water . how many times do you get 1\frac{1}{2} liters of water ?

Answer :-

          no . of jugs are = \frac{34\frac{1}{2} }{1\frac{1}{2} }

                 \frac{\frac{69}{2} }{\frac{3}{2} }

= 23 jugs

your 3 Question :-

                 Q) the cost of 3\frac{3}{4} kg of sugar  is Rs. 121\frac{1}{2} find its cost per 1kg

Answer :-

              Quantity of sugar = 3\frac{3}{4} \\                              = \frac{15}{4} kg\\ Amount = 121\frac{1}{2} Rs .= 243/2 Rs.

by unitary method :-

  \frac{15}{4} kg cost rs. 243/2

therefore

   1 Kg will cost = 243/2 * 4/15\\                       = 16.2 *2\\                       = 32.4 Rs.\\therfore \\     1Kg of sugar will cost Rs 32.4 Rs.

Your 4 Q is :-

     the length of a rectangle field is 12\frac{1}{2} m and its area is 65\frac{1}{3} m^{2} then field its breadth .

Answer :-

             length of ploy = 12\frac{1}{4} = 49/4

             area of plot = 65\frac{1}{3}  = 196/3

             as area = L *b

so,

             \frac{196}{3} = \frac{49}{4} *b

             b = \frac{196}{3} * \frac{4}{49} \\

            b = 5.3 m
