35 of her stickers. What fraction of the yellow stickers was Olivia left with?
|
Silver |
Yellow |
Total |
Comparing silver stickers and yellow 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 silver stickers at first is repeated. Make the number of silver 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 yellow stickers that Olivia was left with
= 6 u - 3 u
= 3 u
Fraction of the yellow stickers that Olivia was left with =
35 Answer(s):
