Question

Write in Indian system of numeration: Three hundred twenty five million four hundred seventy nine thousand eight hundred thirty eight.

Answer 1

Hint: We first break the total amount written in words in three parts according to the units. We find the scalar multiplier for the millions, thousand and unit value. We multiply them and add at the end to find the final solution.

Complete step-by-step answer:
To write down three hundred twenty-five million four hundred seventy-nine thousand eight hundred thirty-eight in Indian system of numeration, we first need to break the total in three parts.
We have three hundred twenty-five million, four hundred seventy-nine thousand, eight hundred and thirty-eight. We find value for each of them in multiplication of their scaler part and add them at the end.
The scalar multiplier for million in three hundred twenty-five million is three hundred twenty-five. This means we multiply 325 with 1000000. We get $325\times 1000000=325000000$.
The scalar multiplier for thousand in four hundred seventy-nine thousand is four hundred seventy-nine thousand. This means we multiply 479 with 1000. We get $479\times 1000=479000$.
We have eight hundred and thirty-eight. We get 838.
We now add them to get
$\begin{align}
  & 325000000+479000+838 \\
 & =325479838 \\
\end{align}$
So, the number of three hundred twenty five million four hundred seventy nine thousand eight hundred thirty eight is 32,54,79,838.
So, the correct answer is “32,54,79,838”.

Note: In all three parts we took the hundreds form for the scalar multipliers. We can break them each one by one, but for all the breaking of a single multiplier the unit remains the same. We can break 325 as $300+20+5$ but the unit for all three of them remains 1 million.
