PSLE At first, Fanny had an equal number of gold and silver stickers . She gave away
34 of her gold stickers and some silver stickers. In the end, she was left with
25 of her stickers. What fraction of the silver stickers was Fanny left with?
|
Gold |
Silver |
Total |
Comparing gold stickers and silver 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 |
The 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 silver stickers that Fanny was left with
= 16 u - 5 u
= 11 u
Fraction of the silver stickers that Fanny was left with =
