27 u |
Comparing between Caden, Gabriel and Zeph in the end |
1x9 = 9 u |
1x9 = 9 u |
1x9 = 9 u |
3x9 = 27 u |
Fraction of stickers that Caden had left
= 1 -
320 -
25 = 1 -
320 -
820 =
920 Total number of stickers
= 3 x 9 u
= 27 u
27 u = 270
1 u = 270 ÷ 27 = 10
Difference in the number of stickers between Gabriel and Zeph at first
