Answer:

At 9:00 P.M.

Step-by-step explanation:

Marcy is taking two types of medicine.

One medicine every 6 hours and other medicine every 4 hours.

She takes both medicines at 9 a.m. now we have to calculate the time at which Marcy take both medicines together again.

We will calculate Lowest common multiple (LCM) of 6 and 4.

LCM of 6, 4 = 2 × 2 × 3 = 12

After 12 hours 9 A.M. = 9 P.M.

After 12 hours at 9 P.M. she will take both medicines together again.
