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.

[[-176, 36, 94, 7, 55, 29], [-66, 24, -23, -199, -43, -40], [-99, -187, -132, -129, 12]]
[94, 24, 12]

[[-170, -186, -15], [-130, -93, -50, 88, -170], [-15, -144, -141], [-85, -104, -115]]
[-15, 88, -15, -85]

[[-38, 18, -74, 21, -169], [39, -11], [-115, -198, -142, -58]]

[21, 39, -58]
