Step-by-step explanation:

the whole process is given in the solution in attached picture. okay

will be the fraction.

Step-by-step explanation:

Here the recurring decimal number is 0.0343434....

To convert this recurring decimal to fraction we assume,

x = 0.03434....   -------(1)

Now multiply both the sides with 100.

100x = 3.43434.... ------(2)

Now subtract equation (1) from equation (2).

100x = 3.43434

     x = 0.03434

99x = 3.4

x =

  =

x =

Therefore, fraction that represents the decimal number is
