Upper primary school mathematics question UPQ419

Hairu and Fatimah are exchanging their stickers with each other. At first, Hairu gives 1/4 of fraction of what he has to Fatimah. Fatimah then gives 208 of her stickers to Hairu. Hairu again gives another 400 of his stickers to Fatimah. In the end, Hairu has 600 stickers and Fatimah has 720 stickers. How many stickers did Hairu have at first?

 Solution:

            By working backward

                        Hairu gives 400 of his stickers to Fatimah

                        The number of sticker that Hairu have before that = 600 + 400 = 1000

                        Fatimah gives Hairu 208 stickers

                        The number of stickers that Hairu have before that = 1000 – 208 = 792

UPQ419-1

                        From the model

                        3 units = 792

                        1 unit = 264

                        The number of stickers that Hairu has at first = 4 × 264 = 1056
