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.

[[-4, -117, -177, -28, -87, -48], [-168, -118, 18, 12, -108, 83, -91]]
[-4, 83]

[[-176, 16, -88, 98, -44], [-156, -113, -11], [25, -32, -27, 98, -103, -77, -111], [8, -82, -157, 26, -176, -52, -180], [-77, -200, -183, -59, -143, 10]]
[98, -11, 98, 26, 10]
