A) 43%
B) 63.7%

If the euro is worth 57% more than the Canadian dollar, it means that if the Canadian dollar is considered to be worth 1 unit, the euro is worth 1 + 0.57 = 1.57 units. To find out how much less the Canadian dollar is worth than the euro, we calculate the difference in their values relative to the euro. The difference is 0.57 units, and when we express this as a percentage of the euro's value (1.57 units), we get (0.57 / 1.57) * 100% ≈ 36.3%.
