Upper primary school mathematics question UPQ471

Hairu, Sarin and Fatimah had a collection of 1 112 stickers. ¼ of Hairu’s sticker collection was 28 stickers more than ½ of Sarin’s collection. Fatimah’s sticker collection is 1/3 of Sarin’s sticker collection. How many stickers did each of them have? 


            ¼ of Hairu’s stickers was 28 more than ½ of Sarin’s stickers

            Draw the math model


            Per the model

                        20 units = 1112 – 4 × 28 = 1000

                        1 unit = 50

                        The number of stickers that Sarin has = 6 × 50 = 300

                        The number of stickers that Hairu has = 12 × 50 + 4 × 28 = 712

                        The number of stickers that Fatimah has = 2 × 50 = 100
