Upper primary school mathematics question UPQ361

Hairu and Fatimah had 1080 stickers altogether. When Fatimah gave 1/6 of her stickers to Hairu, they had the same amount of stickers. How many stickers did Hairu have at first?

 Solution:

            Fatimah gives 1/6 fraction of her stickers to Hairu

            That is to divide the total number of stickers that Fatimah has into 6 equal portions and gives 1 portion to Hairu.

            Fatimah left with 5 portions of her original stickers

            Hairu have same number of stickers as Fatimah after recived from Fatimah the stickers

            Hairu finally has 5 portions of stickers as Fatimah has or Hairu at first has 4 portions of stickers

            In this case, the stickers change hand among them and the total number of stickers remain the same.

            The total number of stickers is 10 portions

            Draw the math model

UPQ361-1

 

            From the above model

            10 units = 1080

            1 unit = 108 stickers

            The number of stickers that Hairu had at first = 4 × 108 = $432
