Rupees and dollars are both units of currency, so one can be converted into the other. Rupees are the currency of India, and dollars are the currency of the United States. (Dollar is the name of the currency of some other countries, but the United States is the largest). The conversion rate changes over time, but the principal is the same.
Find the conversion rate. The conversion rate from rupees to dollars can be found in the business section of large newspapers, at many banks or online at the exchange rates site, x-rates.com. As of late October, 2010, the rate was 1 rupee = 0.022543 dollars.
Multiply by 100.
Write down the result, which, at the time of this writing, would be 2.25 dollars.
