#0.144mg#

Explanation:

the maximum safe dose is #0.06mg//kg//day#. this means that for a #1kg# patient, the maximum safe dose would be #0.06mg//day#.

the patient here is #7.2kg#.
#7.2 * 0.06 = 0.432#
this means that the patient's maximum safe dose is #0.432mg//day#.

the patient takes the drug #3# times a day, so the maximum dose per day is #3# times the maximum safe dose for each time that the drug is taken.
#0.432/3 = 0.144#
this means that the patient's maximum safe dose each time they take the drug is #0.144mg#.
