Solution
Emulsions are colloidal systems in which both the dispersed phase and the dispersion medium are liquids.

Butter is an example of a water-in-oil emulsion, where water is dispersed in fat (oil).
Milk and vanishing cream are examples of oil-in-water (O/W) emulsions, where oil is dispersed in water.
