Some Babylonian tables (translated into Hindu Arabic numerals)

     

What might these tables mean?

Note that, in this notation, commas separate place values (for both whole numbers and fractions).

Can you figure out the common theme here?

Why are certain numbers missing from the left hand column? For example, there is no 7, 11, 13, etc.

How do fractions in the Babylonian style connect with our fractions? (Keep this in mind as we learn about ancient Egyptian fractions later on...)

Could you create a table of this kind with a different number as its focus — for example, 45?
