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: [[-138, -16, -188, -181, 86, -151], [56, -176, 31, -164, 39, 51]]
Example Output: [86, 56]
