-she finds she only has 1/2 cup
-how many brownies could she make?  Let n represent that number

  16%2F%283%2F4%29+=+n%2F%281%2F2%29+    |Cross Multiply to Solve for n 

         8 = (3/4)n
       (4/3)8 = n = 10 Brownies   (Rounding DOWN to the whole brownie.

Write the relevant proportion


    16%2F%28%283%2F4%29%29 = n%2F%28%281%2F2%29%29.


Simplify


    %2816%2A4%29%2F3 = 2n,   or


    64%2F3 = 2n.


Hence,    n = 64%2F%282%2A3%29 = 32%2F3 = 10 2%2F3.


Now round DOWN to the nearest whole numer.



ANSWER.  10 brownies.

Solved.
