There in this question we have a medication that should be given as two doses per day and what we want to know is how many total fluid ounces that would be per day so we want fluid ounces per day.
00:22
So this is our conversion.
00:29
We're trying to complete a unit conversion here so we need some equalities that are going to allow us to do that so first of all, we have two doses per day.
00:38
We need to know how much medication there is in a dose well, the problem tells us that one dose is 30 milliliters, but we don't want an answer in milliliters we want an answer in fluid ounces.
00:53
So we need an equality between fluid ounce and milliliters, so we find that one fluid ounce.
01:01
Actually, let me go ahead and write that out instead of abbreviating so one fluid ounce is equal to 29 .57 milliliters.
01:15
Okay, so we have all of the information we need now to complete our conversion let's go ahead and set this up using dimensional analysis so we are starting off knowing that we need to give the child two doses of this medication each day and first thing i want to do is to convert doses to milliliters so i'm going to use my first equality there in every dose.
01:44
We know there are 30 milliliters.
01:48
I wanted to put dose in the denominator because i want the term dose to cancel so if we were to solve this now, we would know the number of milliliters we need each day but that's not what we want...
