Partial differentiation of a function with more than one variables refers to its derivative being taken with respect to one of those variables, while the rest being held as a constant.
An example is the volume of a cylinder given by:

The volume requires two variables in order to work out the volume, namely the radius and the height.
Using partial differentiation, its partial derivative can become:

This symbol is used in place of the derivative symbol, in order to distinguish total derivatives and partial derivatives.
Answer:

Step-by-step explanation:
The full page would be represented by 1= 12/12 or 12*1/12, the you would have to multiply the time 1/3 by 12 = 12*1/3 =12/3= 4.
