Question

Translate the following into a mathematical equation:
The density D of a material is directly proportional to the mass of the object M and inversely proportional to its volume V.

Answer 1

Answer:  D = M/V

This equation says that D is proportional to M and that D is inversely proportional to V.
D = density
M = mass
V = volume

The constant of proportionality is taken as 1.
