Hi, so to solve for this, we're going to use dimensional analysis.
00:06
The first question is the amount of the medicine that the patient will need to take in terms of teaspoons.
00:15
So just the right number of teaspoons per dose.
00:27
If the patient needs to take 250 mg and then the available suspended medicine is 125 mg for every 5 ml.
00:40
So we'll write ml in the numerator.
00:43
Then we'll convert ml to teaspoon.
00:45
This is the conversion factor.
00:47
We'll write 1 teaspoon in the numerator and 4 .93 ml in the denominator.
00:53
So 1 teaspoon is equivalent to 4 .93 ml.
00:56
Now we could cancel.
00:59
Oh, sorry, i forgot to write here.
01:02
This is per dose.
01:05
So we can now cancel some units.
01:07
We could cancel milligrams and then ml.
01:09
The remaining units, as you can see, we have teaspoon per dose.
01:13
And this will give us 2 .028 teaspoons...
