Upper primary school mathematics question UPQ390
Hairu had 3/5 as many stickers as Fatimah. For every 10 stickers Fatimah had, Sarin had 4 stickers. If Hairu had 246 stickers, find the number of stickers that Sarin had.
Hairu’s stickers is 3/5 of Fatimah’s stickers
For every 10 stickers Fatimah had, Sarin had 4 stickers
It means every 5 stickers that Fatimah had, Sarin had 2 stickers
Or, Sarin’s stickers is 2/5 of Fatimah’s stickers
Draw the model,
From the model
3 units = 246
1 unit = 82 stickers
The number of stickers that Sarin had = 2 × 82 = 164
You can also work out by first determine the number of stickers that Fatimah have then based on the given info. of every 10 stickers that Fatimah had, Sarin had 4 stickers to determine the number of stickers that Sarin had.
Hairu’s stickers, 3 units ==> 246
Fatimah’s stickers, 5 units ==> 5 × 246 ÷ 3 = 410
Sarin’s stickers = 4 × 410 ÷ 10 = 164
