In France grapes are 1.68 Euros per kg. What is the cost of grapes in dollars per pound if the exchange rate is 1.39 dollars per EUro

Multiply the price of the grape by the exchange rate to get the dollar/kg unit,

Euro/kg * Dollar/Euro = Dollar/kg

One 1Kg = 2.2 pound

So we have, 1.68 Euro/kg * 1.39 Dollar/Euro * 1Kg/2.2lb

[1.68 * 1.39] / 2.2 = 1.06

Thus, the cost of grapes in dollar per pound is $1.06.

(1.39 dollars/Euro) x (1.68 Euro/1 kg) x (1 kg/2.2 lbs) = 1.06 dollars/lb
