Multiply (as a Babylonian): 141 times 17 1/5

Question

How do we multiply 141 times 17 1/5 as a Babylonian? I wasn't sure the space between 17 and 1/5, now I see that 17 1/5 is 17.2 in our notation.

Is there a formula that I can solve this?

Any hint, comment would be very appreciated it!

Answer 1

Hint: Note that ${1\over5} = {12\over 60}$, and try to write both numbers in sexagesimal notation. Then multiply in the same way as we multiply numbers in decimal notation. (The Babylonians would have multiplication tables to help them with this.)
