It's 640, and you can figure this out with just logic. 45% is just under half, and 288 X 2 is definitely over 343, so the logical answer is 640.

That is a classic word problem.
Say that N is the number of students in the school.
Then .45 N = 288
Now divide both sides of that equation by .45 to get N to be by itself on the left side.
You get 640 kids in the school from the arithmetic.

set up a proportion
45/100 = 288/x
cross multiply
45x = 28800
divide by 45
x = 640
there are 640 kids in teh school.

x=number of kids in school
45%*x=288
x=288/45%
x=288/.45
x=640

640, because you do 288 divided by 0.45 equals 640 : )
