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.
1/3times13/4=? (Equation)
=1/3times7/4 (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 13/4 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!
