First, of all, you need to be more polite when you ask people for help. No one on this site is getting paid for their time. We do this because we want to help you learn. Your messages in this thread have bordered on rude and your demand that we "solve" your homework problems is not the best way to get our help.

40) if there are 340 people 18-24 out of every 1000 moviegoers then the ratio of 18-24 year old moviegoers is 340:1000 which reduces to 17:50. Ratios reduce the same way fractions do.

46) I misunderstood this question the first time you asked it. A screw will move the length of the pitch after one full rotation which means if you turn the screw counterclockwise ten times it will come out 10 times the length of the pitch. 10 * 3/32 = 30/32 = 15/16 inches

52) I answered this question already. You need to figure out 1/3 of 7/10 which is:
(1/3)*(7/10) = 7/30
So 7/30 of Americans eat fast food sandwiches for lunch.

I am told that this is part of a test that folks are expected to answer on their own for a score. If that is so, I don't wish to participate in misrepresentation or cheating.
