#1 1/2# cups

4 dozen cookies is exactly double 2 dozen cookies, so the amount of sugar will be double as well.

#3/4 xx 2 = 6/4#

#= 3/2 = 1 1/2#

#1 1/2 # cups of sugar are needed.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can also add #3/4 +3/4#

#= 3/4 + (1/4 +2/4)#

#= (3/4 +1/4) +1/2#

#= 1 +1/2#

#= 1 1/2#
