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, -128, -21, -121, -117, -92], [-48, -9, -141, -18, -95], [-20, -29, -22, -193]]
[99, -9, -20]

[[-152, -12], [10, -52], [-104, 77], [73, -72, 72]]
[-12, 10, 77, 73]

[[-55, -2, -68], [-65, 20]]

[-2, 20]
