In this task, you are given a list. This list contains many lists of integers. The list is several items written within a []. Your task is to find the maximum number among the members of each inner list. The output should be a list comprised of the maximums with the same order as the internal lists.

Example Input: [[91, -82, -158, -188], [-148, -168, 25, 53], [-87, 82], [-176, -136, -24, -72, -9, -12]]
Example Output: [91, 53, 82, -9]

Example Input: [[-37, -136, 90, -104], [-33, -60, -12], [-7, -27, 100, -101, -172], [6, -150, -75]]
Example Output: [90, -12, 100, 6]

Example Input: [[-169, 53, 21, -86, -129], [-90, -53, 37, -51, 75, -10, -32], [-113, 40]]
Example Output:
[53, 75, 40]
