You want to perfect your homemade pizza crust, so you decide to do a little experiment. You want to compare different kinds of flour to see which one makes the best pizza crust. Your problem is that the recipes you have all give the amount of flour in ounces, and you only have cups.

The table below gives the conversions between volume and ounces of different kinds of flour.

Kind of Flour	Volume	Ounces
Bread Flour	1 cup	`4.5`
European-Style Artisan Bread Flour	1 cup	`3.75`
Perfect Pizza Blend Flour	1 cup	`4.25`
White Whole Wheat Flour	1 cup	`4.75`
Unbleached All-Purpose Flour	1 cup	`4`

Given that your recipe calls for 13.25 ounces of Unbleached All-Purpose Flour how many cups will you need? Enter your answer as a fraction or decimal.
