PSLE At first, Nicole had an equal number of gold and yellow stickers . She gave away
34 of her gold stickers and some yellow stickers. In the end, she was left with
25 of her stickers. What fraction of the yellow stickers did Nicole give away?

Comparing gold stickers and yellow stickers at first |
1x4x5 = 20 u |
1x4x5 = 20 u |
2x4x5 = 40 u |
Before |
4x5 = 20 u |
20 u |
5x8 = 40 u |
Change |
- 3x5 = - 15 u |
- 9 u |
- 2x8 = - 24 u |
After |
1x5 = 5 u |
11 u |
3x8 = 16 u |
After
1x5 =
5 u11 u
3x8 =
16 uThe number of gold stickers at first is repeated. Make the number of gold stickers the first the same. LCM of 4 and 1 is 4.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 8 and 5 is 40.
Number of yellow stickers that Nicole was left with
= 16 u - 5 u
= 11 u
Number of yellow stickers that Nicole gave away
= 20 u - 11 u
= 9 u
Fraction of the yellow stickers that Nicole gave away =
