Since X is positive, multiplying or dividing both sides of an inequality by X will not change the direction of the inequality- 1090519040/X< Y< 12184453140/X. Since X is at most 255, what is thesmallestY can be? Since X can be any positive number, what does that tell you about how large Y can be? Note that since X and XY must be integers, Y may not be an integer.
