1- The percentage change in the value of the Ecuadorian Sucre was an increase of 400%.

2- The change in the percentage of the value of the Brazilian Real was a decrease of 32.77% of its value.

Explanation:

1- Given that the Ecuadorian sucre (S) suffered from hyper-inflationary forces throughout 1999, and its value moved from S5,000 / $ to S25,000 / $, to determine what was the percentage change in its value, the following calculation:

5000 = 100

25000 = X

25000 x 100/5000 = X

2500000/5000 = X

500 = X

500 - 100 = 400

Therefore, the percentage change in the value of the Ecuadorian Sucre was an increase of 400%.

2- Given that the Brazilian reais (R $) value was R $ 1.80 / $ on Thursday, January 24, 2008, and its value fell to R $ 2.39 / $ on Monday, January 26, 2009, to determine what was the percentage change in its value the following calculation must be performed:

1.80 = 100

2.39 = X

2.39 x 100 / 1.8 = X

239 / 1.8 = X

132.77 = X

132.77 - 100 = 32.77

Therefore, the change in the percentage of the value of the Brazilian Real was a decrease of 32.77% of its value.
