We have one quart for every 2 pints, or you can view this as 2 pints per quart or 1 2 of a quart per pint.

You have 2 pints per quart.

Or 1 4 of a gallon per quart.

Now we know that there are 2 pints per quart.

Or we can view it this way, we want the pints to cancel out, or 1 quart is 2 pints, or 1 2 quart per pint.

Or you could say that you have 32 fluid ounces per quart.

So you have 4 quarts per gallon times 2 pints per quart.

So this quart that I drew here, I can divide it into 2,

So this right here that I've just drawn in blue would be exactly 1 quart.

2 of these combined make 1 quart, so 4 of them is going to be 2 quarts.

And it's going to be smaller by a factor of 2 because you have 2 pints per quart.

So if I were to draw the quarts here, I could divide this gallon into 4 quarts, and then each of these sections would be a quart.

Because when you're just doing it, you don't have paper, you don't have the units around, you should just think, hey, 80 pints, there's 2 pints per quart.

Actually, I'll give you a little bit of overview of how many cups there are in a pint, how many pints in a quart, and how many quarts in a gallon.

But when problems get a little bit more complicated, it is nice to make sure that the units cancel out in this way, so that you know, OK, 1 quart is 2 pints.
