Change 2 |
- 4 u |

After |
5 u |
5 u |
5 u |
15 u |
Comparing between Caden, Owen and Tom in the end |
1x5 = 5 u |
1x5 = 5 u |
1x5 = 5 u |
3x5 = 15 u |
Fraction of stickers that Caden had left
= 1 -
110 -
25 = 1 -
110 -
410 =
510 Total number of stickers
= 3 x 5 u
= 15 u
15 u = 285
1 u = 285 ÷ 15 = 19
