Okay, it sounds like you need to learn how to do the basics of percentages.
When it's an "a is what percent of b" question, then you want to set it up as a = b*x, and solve for x. Let's go through the first example:
24 = x*32.
Divide both sides by 32 to get x = 24/32.
Reduce fraction to get 3/4, which is 75% (if converting fractions to decimals throws you, message me for help on that).
When it's "What percent of A is B?" then it's x = B/A
We'll do the second one as an example:
x = 23/230
Reduce to get 1/10, which is 10%.
Number nine is the only one that looks different, but it's actually the same question. The only trick is to figure out how many hours are between 8am and 2pm!
As always, if you need further clarification or want to check your answers, please feel free to email me.

I am maths teacher sending you this tips: 1) Do not fix specified time, 2) Interest is the motivating factor to learn mathematics. 3) very most important point to be noted is "Practice Examples and Exercises only. 4) Do not omit any chapter. 5) if you are a student of state board,do not learn anything from out side the Text Book. 6) Refer previous year questions. 6) if ISC, you should refer extra books. 7) Interest and hard work with confident would bring you 100%successes

It's too much to tackle all at once if you post this many.
The first one is 24/32 = 3/4 = 75%
The 2nd one is 23/230 = 1/10 = 10%
And so on and so forth. Good luck!

1. 24 is what percent of 32
2. What percent of 230 is 23=10%
3. What percent of 25 is 23=92% or (23/25)(100)
4. What percent of 400 is 8=2%
5.21 is what percent of 168=12.5% or (21/168)(100)
6. 246 is what percent of 656 =37.5% or (246/656)(100)
7. 364 is what percent of 455=80% or (364/455)(100)
8. what percent of 600 is 84=14% or (84/600)(100)
9. 8:00am to 2:00pm for what percent of a 24 hour day is that=14hres(pm)-8hres(am)=6hres= 25% (6/24)(100)
11.what percent of 40 is 28=70% (28/40)(100)
