Don't be intimidated by fractions.
Remember that if you have x/4, that's the same as x *(1/4). And 1/4 = 0.25, so x/4 is just equal to 0.25x.
Does that make it easier to work with?
Talk to your teacher mate. Getting the answers of here won't help you learn.

X/4-x/2 < 3/2
-x/2 <3/2
x<-3

x>-6 because:
x/4 - 1/2 < x/2 + 1 (original equation)
x/4 - 2/4 < 2x/4 + 4/4 (common denominators)
(x-2)/4 < (2x+4)/4 (combine fractions)
x-2 < 2x+4 (multiply 4 to each side)
x-6 < 2x (subtract 4 from each side)
-6 < x (subtract x from each side)

x/4 - 1/2 < x/2 +1
x/4 - x/2 < 1+ 1/2
-x/4 < 3/2
-x < 12/2
-x < 6
x > -6
that's right

use 4 as the lcd
x-2<2x+4
-x<6
x>-6

Let's see.... I am willing to go with x=16. It took me a bit to figure that one out.
