Zoe uses 1/3 of her money to buy a dress and 1/4 of the remaining amount to buy some magazines. After that, she uses 2/5 of the rest of the money to buy a present. If she has $54 left, how much money did she spend on the magazines? This is a question that requires students to understand that 3 units of one model is actually equivalent to another number of units of another model. With an understanding of the concept and more practice of such questions, a student should be able to handle such questions easily in future.Jia Ying Sin
