46) We need to know how thick the piece of plywood is to determine this answer.

52) You want to find what 1/3 of 7/10 is. The word "of" implies multiplication.
1/3 * 7/10 = 7/30
7/30 of Americans eat fast food sandwiches for lunch.

62) I'm not sure what you want me to do with these two numbers. If you add them, you get 36 yards.
If you're trying to find the area of something that is 18 yards by 18 yards multiply 18 by 18 to get 324 square yards.

64) Again, I don't know what you want me to do with these numbers. If you add them, you'll have to use a common denominator of 5: 17/5 + 20/5 = 37/5 kilometers
If you're looking for an area than multiply them to get 68/5 square kilometers.

24 is a composite number because it has more factors than just 24 and 1. 1,2,3,4,6,8,12,24 are all the
factors of 24.

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.
