In france, grapes are 1.75 euros per kilogram. what is the cost of grapes in dollars per pound if the exchange rate is 1.36 dollars to 1 euro? ( hint: covert 1 until at a time.) ( remember: 1 1b =454g)

You want to convert Euros / kg to Dollars / pound

So you'll have to multiply the price (Euros / kg) by the exchange rate (Dollars / Euro) to get a number that has units of Dollars / kg.

Euros     Dollars       Dollars

 x   =  

 kg         Euro             kg

Then you have to multiply the number of kg in a pound (which has units of kg / pound) to get a number in units of Dollars / pound.  This number is 2.2.

Dollars       kg              Dollars

 x   =      

  kg        pound           pound

So the answer would be 1.75 * 1.36 / 2.2 = 1.08 dollars / pound.
