In this problem, we're just doing unit conversions.
00:02
We want to convert the price of gasoline in canada to the price of gasoline in the u .s.
00:08
So we know that in canada, the gas costs $1 .07 canadian dollars per liter.
00:13
That's going to be the rate that we start with.
00:16
1 .07 canadian dollars for one liter.
00:23
Okay.
00:23
Now we want to make a conversion, and it doesn't matter where you start, but basically you have to change canadian dollars to u .s.
00:30
Dollars and liters to gallons.
00:32
Let's start with the dollar.
00:34
So it says one u .s.
00:36
Dollar is equal to $1 .17 in canadian.
00:40
So i'm going to multiply.
00:42
I want to cancel out the canadian dollars.
00:44
That's going to go on bottom.
00:46
And it's $1 .17 in canadian dollars is one u .s...
