Question 972216
Two cups of flour is half of four cups of flour.  Do the same to the milk.  PROPORTION!


{{{(1+1/10)/2}}}



{{{(10/10+1/10)/2}}}


{{{(11/10)/2}}}


{{{11/(10*2)}}}


{{{11/20}}}, which is a little more than half a cup.  One would use HALF a cup, in actual practice, because the {{{1/20}}} of a cup part is too much accuracy to read the cup's measurement markings.
