Try to do this with _money_. Say that you want to buy her a Ferrari, and its price is 0.4545_ million dollars. Now, you want to convert this to a fraction. So, you get the price of a hundred Ferraris, or 45.4545_ million dollars.
If a hundred Ferraris cost 45.4545_ million dollars and one Ferrari costs 0.4545_ million dollarars, then 99 Ferraris would cost 45 million dollars. Etc. Veritatis simplex oratio est Alberto Monteiro
