Just 3, as in the question. You cannot get simpler that that!
Since 19 is prime and has no other factor that is not one out itself, there is no simpler form.
1/5 is in its simplest form.Any integer can be expressed as a fraction in its simplest form by putting it over 1.
1/19 in simplest form is still 1/19; the number cannot be broken down anymore and therefore is already in simplest form. However, in decimal form it is 0.053.

Atoms.
An element cannot be chemically broken down into simpler substances. Elements are the simplest form of matter and are made up of a specific type of atom. Elements can only be transformed through nuclear reactions, such as radioactive decay or nuclear fusion.
Atoms of the elements are the simplest particles of compounds. The definition of an element is a substance that cannot be broken down into a simpler substance or interconverted.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
They are the simplest of substances and cannot be broken down into any other substance.
Helium is a chemical element and is the simplest and lightest noble gas in the periodic table. It cannot be broken down into simpler substances by chemical reactions, as it consists of only helium atoms.

No, it can be broken down.
The periodic table itself cannot be broken down into simpler substances because it is a tabular arrangement of all the known chemical elements. Each element on the periodic table is a fundamental substance that cannot be further broken down into simpler substances by ordinary chemical processes.
