#3/2z+3/2#

Explanation:

#50%=1/2#

Let #s# be such an expression that #s=#50% of 1/20 of the product of 12 and 5z+5

#s=1/2(1/20(12(5z+5)))#
#=1/2(1/20(60z+60))#
#=1/2(3z+3)#
#=3/2(z+1)#

Personally you can leave it there; it is factored into 1 set of brackets with integers inside the brackets, although likely the question wants you to expand the brackets fully.

#s=3/2z+3/2#
