anonymous · Answer

Garette has to take 2tsps 3 times per day, so in one day, he will take 2 x 3 = 6tsps per day.  One tsp contains 5mL.  Garret takes six of these, so he takes 6 x 5mL = 30mL.

So now we know how much he takes in a day.  We want to find out how many days worth of medicine there is in the bottle.  One day tales out 30mL, and we have 120mL to share out, so the number of days will be 120mL/(30mL per day) =4 days.
