<PRE><B>Question 1010433</B>
A recipe for chocolate chip cookies calls for 3/4 cup brown sugar for every 2 1/4 cups of flour. 
If 2 5/8 cups of brown sugar are used, how much flour will be needed? 
----
Use a proportion::
flour/sugar = flour/sugar
----
f/(2 5/8) = (2 1/4)/(3/4)
-------
f/(21/8) = (9/4)/(3/4)
----
f/(21/8) = 3
---
f = (21/8)3
f = 63/8
f  = 7 7/8 cups
---------
Cheers,
Stan H.
