First of all, do not put so many questions all into one posting, please.
Your answers are correct, except the following:
11) I got 121.91
16) should be 78
31)
18w + w + (10/7)w ??
= (306w+17w+10w)/17
= (333/17)w
33) is it (x2)/3 = 4/5 ??, if so then
5x  10 = 12 ( I multiplied both sides by 15
5x = 22
x = 22/5 
thank you but I still do not get 33.
the question is
x minus the fraction 2/3 = the fraction 4/5. to get the answer i would add the fraction 2/3 to the fraction 4/5 which gets me x = 22/15, right? 
yes, if that is how the question was written.
you had posted:
x  2/3fraction = 4/5fraction
which I had interpreted as
(x2)/3 = 4/5
the answer I provided reflected that version.
Your original question with the word "fraction" inserted was quite confusing. 
During a year, a person saves 1500 dollars? What is the corresponding number for this sentence?

simplify 19.(30)57
