Gino studied for 5/4 hours in all. To get this, do 3+2 for the numerator and just put 4 as the denominator. (Four just stays the same the denominator is all fours. If you want more details just put it on comments.) Now you have the answer: 5/4 hours.
Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
