Complete step-by-step answer:
We are given that the number is an 8-digit number in the international system.
We know that the international system has the concept of ones, tens, hundreds, thousands, ten thousands, hundred thousands, million, ten millions and so on, whereas Indian system has place values of ones, tens, thousands, ten thousands, lakhs, ten lakhs and so on.
