Achild is to receive a dose of 0.5 teaspoon of cough medicine every 6 hours. if the bottle contains 24 doses, how many days will the medicine last?

Well, to find this out, lets find out how much is taken each day:

6 hours x 4 = 24 hours (Or one day)

So because we multiplied the hours by 4, we also multiply the dosage by 4:

.5 ts x 4 = 2 ts

That means every day, 2 teaspoons is taken by the child.

Then we figure out how many teaspoons of medicine there is in 24 doses:

If .5 ts = 1 dose, then 12 ts= 24 doses because half a teaspoon is 1 dose.

So if there are 12 ts and and 2 ts are taken each day, then that means the final answer is:

The medicine will last 6 days.

Hope this helps!
