Step 1: First, consider the sublist [18, 13]. Divide the first number in this list i. e. 18 by the second number in this list i. e. 13 using list indexing method. Step 2: Next, consider the second sublist [4, 5]. Divide the first number in this list i. e. 4 by the second number in this list i. e. 5 using list indexing method. There can be more than two sublists. So, perform Step 1 and Step 2 using for loop.

Step 3: Calculate the sum of fractions by adding the results obtained in Step 1 and Step 2.

Step 4: Round off the result to the nearest whole number using the round() function. The syntax of round() function is:

Syntax: round(float_num, num_of_decimals)
