They have to be the same.
Density = mass / volume. An object will float if it has less density than the fluid in which it is placed. The buoyant force is equal to the volume (this may be the submerged part of the volume) times the density of the displaced fluid.
The density of an object is related to the density of the fluid it is in because if the density of the object is less than the fluid than it will float. If this density of the object is greater than the density of the fluid it will sink to the bottom.
If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
The object's density.If less than the density of the fluid, the object floats.If more than the density of the fluid, the object sinks.

When you have the density of both the object and the fluid, just see which has a higher density. If the object has a higher density than the fluid, the object will sink. If the object has a lower density than the fluid, the object will float.

density of the object < density of the fluid
An object would float on a fluid if the density of the object was less than the density of the fluid.
If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
The object's density.If less than the density of the fluid, the object floats.If more than the density of the fluid, the object sinks.
To know this you first need to find the density of the object and the density of the fluid on which the the object shall be kept. If the density of the fluid is more than the object's density then the object will float. The object will sink if the reverse happens.
If the object's density is greater than the density of the fluid you put it in, then it sinks. If less, then it floats in that fluid.
it is the density of a fluid (the operation for finding the density of an object is mass divided by volume)
