Alright, so first we should add up all of the teachers to get the gist of how many there are in each school.
I got 50 in both North MS and West MS.
F. Half of the teachers would be 25. music+cooking=25 teachers. Correct.
But now, we need to find percentages.
Convert the problem to an equation using the percentage formula: P% * X = Y.
30%x50= 15. Does 9+6 equal 15? Yes, F is Correct.
G. A quarter of 50 is 12.5. (There can't be decimals of teachers though.) At West MS 11 teachers enjoy reading and 14 enjoy outdoor recreation. 11 is less than 12.5 and 14 is more. Incorrect.
H. A majority means more than half in simple terms. Do more than half of the teachers at North MS enjoy rec and cooking? (6+19) It's tricky as there's 25 teachers. However, it is not greater than 25 so it is not a majority. Incorrect.
J. Less than half of 50 teachers at West MS enjoy rec and music. (14+15=29)
Incorrect.
Hope this helped! Khan Academy is a fantastic resource.

Since it is super-urgent, it is probably a test or quiz. I should not have answered the question. I will help by giving you an example. You will need to work it out using a calculator. This is the best I can do.
Well, you just divide 7056 by a guess number x.
Take the average of x and the quotient (result of division) and repeat again.
Example:
Find square-root of 700, with an initial guess of x=27.
The quotient is 25.92592592592592
Taking average of 25.92592592592592 and 27 gives 26.46296296296296.
Using new guess x=26.46296296296296 and repeat the same process, we get 26.45751367182438
Using the new guess x=26.45751367182438 and repeat the same process, we get 26.45751311064591 which is accurate to 13 places after the decimal.
If it is not clear, try finding square-root of 625 and the final answer should be 25 (exactly) after three or four repetitions.
