This question gives me two statements and then ask me what are the following four statements is false.
00:10
Let's take a look at those four.
00:13
Let's start with a.
00:15
A says pr is less than qr.
00:21
Now, i have no idea if p and q are negative numbers, positive numbers, or one of each.
00:31
So i need to solve this a different way.
00:34
I'm going to solve.
00:35
It algebraically, i'm going to take each side of this equation and divide by r.
00:43
So these r's make a 1, and these r's make a 1, and that leaves me with a statement, p is less than q, which i know to be true.
00:58
So let's try b.
01:02
B says pr is greater than pq, q, sorry.
01:10
So let's do the same strategy...
