#16# is #1/3# of #48#. So then, the recipe for #16# cookies would be #1/3# of the recipe for #48# cookies. The amount of butter we need #1/3# of the butter for #48# cookies.
#1/3##times##1##3/4##=?# (Equation)
#=##1/3##times##7/4# (Changed the mixed fraction to an improper fraction.)
#=##7/12# (Multiplied and solved!)
The amount of butter Howie and Steve need for #16# cookies is #7/12#! Though you didn't tell me the measure like #1##3/4# of a cup or something, make sure that you add of something to the #7/12#! And by something, I mean a cup or something like that.
I don't really have any sources to list because I just used my mind. I hope you understand the explanation!
