Solution

Intensive properties :- The properties of the system which depend only on the nature of matter but not on the quantity of matter are called intensive properties.
Here, Mass and volume are extensive properties. But ratio of two extensive properties is always intensive properties.
$$\therefore \quad \dfrac { Mass }{ Volume } =Density=Intensive\quad property$$
$$\dfrac { Volume }{ Mass } =\dfrac { 1 }{ Density } =Intensive\quad property$$.
