14 of her stickers. What fraction of the silver stickers did Anna give away?

Total |
Comparing blue stickers and silver stickers at first |
1x3x2 = 6 u |
1x3x2 = 6 u |
2x3x2 = 12 u |
Before |
3x2 = 6 u |
6 u |
4x3 = 12 u |
Change |
- 2x2 = - 4 u |
- 5 u |
- 1x3 = - 9 u |
After |
1x2 = 2 u |
1 u |
3x3 = 3 u |
After
1x2 =
2 u1 u
3x3 =
3 uThe number of blue stickers at first is repeated. Make the number of blue stickers the first the same. LCM of 3 and 1 is 3.
The total number of stickers at first is repeated. Make the total number of stickers at first the same. LCM of 6 and 4 is 12.
Number of silver stickers that Anna was left with
= 3 u - 2 u
= 1 u
Number of silver stickers that Anna gave away
= 6 u - 1 u
= 5 u
Fraction of the silver stickers that Anna gave away =
