Final answer:
To convert dollars into another currency, multiply the amount in dollars by the exchange rate of the foreign currency per dollar. The exact method depends on how the exchange rate is expressed, using either direct or inverse ratios depending on the currency pair involved.
Step-by-step explanation:
To convert U.S. dollars into another currency, one must multiply the number of dollars by the exchange rate of the foreign currency per dollar. If the exchange rate is expressed in foreign currency units per dollar, you use multiplication. For instance, if the exchange rate is 5.50 Turkish Lira per U.S. dollar and you have $100, you multiply 100 by 5.50 to get 550 Turkish Lira. However, in a situation like the French firm mentioned, where the conversion is from dollars to euros, you would take the dollars and multiply by the inverse of the exchange rate (since it's expressed as dollars per euro), i.e., $10 million × (€1/$1.37) to get the amount in euros.
