Hey mate

rrelative atomic mass of an element is the ratio between the average mass of its isotopes to one twelveth part of the mass of a carbon-12 atom. It is denoted as Ar.

It is otherwise called "standard atomic weight".

Relative atomic mass = average mass of isotopes the element/1/12th after the mass of one carbon -12 atom

Hope this helps you
