Arrange the following integers in descending order:

-24, 16, -40, -5, -13, 6, -1

Given positive integers are 16, 6.
In descending order they are 16 > 6.

Given negative integers are −24, −40, −5, −13, −1.
In descending order they are −1 > −5 > −13 > −24 > −40.

Hence, all the given integers in descending order are:
16 > 6 > −1 > −5 > −13 > −24 > −40.

i.e., 16, 6, −1, −5, −13, −24, −40.
