Awoman bought a dress at a discount of 16 2/3. if the woman paid 32.50, what was the original price of the dress

The original price = what the woman paid + discount
                           = 32.50 + 16 2/3
                           = 32.50 +  50/3

convert to one form of fractions (improper or decimal)
                           = 49 1/6
                           = 49.16



In case of 16 2/3 % discount of the original price:

price after discount = price before discount - discount
                               = x - 16 2/3 % of x
                               = x -  01667x
                               = 0.833 x
                       32.5 = 0.833 x

then x = 32.5/0.833 = 39.015 =~ 39

hope that helps
