   40 = x
__
b) (x/180)(180) = (4/9)(180) 
   x = 80
__
c) (7/11)(121) = (x/121)(121)
   77 = x
__

Time to work it out 
32 - 8 + 2 - 1/2
32 - 8 + 2 = 26
now you have
-1/2 + 26 
so we convert 26 to fraction form to subtract 
26/1 - 1/2
we must find the common denominator
52/2 - 1/2
51/2
fifty-one over 2 (fraction) is your answer! :)
