If the Canadian dollar is worth 18% less than the U.S. dollar, it means that if the U.S. dollar is considered to be worth 1, the Canadian dollar is worth 0.82 (100% - 18% = 82%). To find out by what percentage the U.S. dollar exceeds the Canadian dollar, we calculate the difference in their values relative to the value of the Canadian dollar: (1 - 0.82) / 0.82 = 0.2195 or 21.95%.
