35 of her stickers. What fraction of the silver stickers was Roshel left with?
|
Yellow |
Silver |
Total |
Comparing yellow stickers and silver stickers at first |
1x5x1 = 5 u |
1x5x1 = 5 u |
2x5x1 = 10 u |
Before |
5x1 = 5 u |
5 u |
5x2 = 10 u |
Change |
- 2x1 = - 2 u |
- 2 u |
- 3x2 = - 4 u |
After |
3x1 = 3 u |
3 u |
2x2 = 6 u |
The number of yellow stickers at first is repeated. Make the number of yellow stickers the first the same. LCM of 5 and 1 is 5.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 10 and 5 is 10.
Number of silver stickers that Roshel was left with
= 6 u - 3 u
= 3 u
Fraction of the silver stickers that Roshel was left with =
35 Answer(s):
35
