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.
