Payment for every cooking pot sold = $5 Total payment for every group of 8 pots sold = $5 x 8 + $20 = $60 Maximum groups of 8 pots sold = $500 / $60 = 8.3 = 8 groups (round down to nearest whole number) 8 x $60 = $480 $500 - $480 = $20 Number of pots sold apart from groups of 8 pots = $20 / $5 = 4 Total number of pots sold = 8 x 8 + 4 = 64 + 4 = 68 pots

SG Primary 5 Fractions

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
