A recipe for 60 cookies required 1 1/4 cup of sugar
----------------
Half as many cookies require 1/2 as much sugar, so
----------------
30 cookies require 1/2 + 1/8 = 5/8 cup of sugar
----------------
15 cookies require 1/4 + 1/16 = 5/16 cup of sugar
----------------
3 times this many cookies require 3 times this much sugar, so
----------------
45 cookies require 3/4 + 3/16 = 15/16 cup of sugar
