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.

[[99, -101, -88, 15, -73], [38, -143, -93, 43, -104, 48], [-39, -90, 31], [-146, 49, -10, 77, -49, -177]]
[99, 48, 31, 77]

[[-50, -44, 70, -90], [-191, 56, -90, -125, -64], [-86, -22]]
[70, 56, -22]

[[99, -35], [-44, -111, -133, -79, -94, -104]]

[99, -44]
