Upper primary school mathematics question UPQ430
Hairu had some stickers. He gave 18 stickers to Fatimah and 5/7 of the stickers to Sarin. Then, he used 3/4 of the remainder for his project and had 35 stickers left. How many stickers did he have at first?
Draw the stickers’ flow diagram
From the stickers flow
The 1/4 fraction of the remainder is 35 stickers
1 unit = 35
The reminder stickers = 4 × 35 = 140
The 2/7 fraction of Hairu stickers = 140 + 18 = 158 stickers
2 units = 158
1 unit = 79 stickers
The number of stickers Hairu has at first = 7 × 79 = 553
