If you're a doctor prescribed a medicine and you had to take 0 .1 milligrams every day, so daily you had to take 0 .1 milligrams, you were given a liquid form of the medicine and the dosage is 0 .5 milligrams per milliliter.
00:16
We have to find the correct dose.
00:19
So what we're going to do is we are going to break apart this liquid form here.
00:26
What this says, and i'm going to rewrite it really quick, this is actually a ratio.
00:36
It's a ratio of 0 .05 milligrams per every one milliliter.
00:44
So you can write it like this as a fraction or 0 .05 milligrams for every, or you can use the per, and this is one milliliter.
01:01
So if you are given one milliliter, you are going to get 0 .5 milligrams of the medicine.
01:09
So what we need to do is we're going to set up our, sort of like a ratio, a multiplication of ratios, 0 .1 milligrams.
01:22
We're going to multiply that by our ratio...
