Hi there, in this question, we need to set up an equation and solve for our answer here.
00:09
And what we mean by that is we're going to be doing a unit conversion.
00:13
We are starting with the units microgram per deciliter, and we are trying to get to the units grams per milliliter.
00:27
Okay, so that means we need to do two conversions here.
00:30
We need to convert from micrograms to grams, and we need to convert from december.
00:34
To milliliter.
00:36
Well, microgram means 10 to the negative 6th.
00:40
So that means there's one times 10 to the 6th of these small little micrograms in every gram.
00:48
And in every deciliter, dese means 10 to the negative 1, while milly means 10 to the negative 3rd.
00:56
So there's a difference of 10 to the second or 100.
00:59
So there's 100 of the smaller units, milliliter, in one decaliter.
01:04
So we need to use these two equalities for our conversion.
01:08
Let's go ahead and set this up and then solve for our answer.
01:14
So we have 42 micrograms per deciliter.
01:20
That's what we are given.
01:23
And we need to convert the numerator to grams...
