- Number of stickers that Bryan has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Charlie and Bryan = _____ u

5 u |
10 u |
4 u |
(b)
LCM of 1 and 5 = 5
Number of stickers that Bryan has = 4 u
(c)
Total number of stickers that the children have
= 5 u + 10 u + 4 u
= 19 u
(d)
Difference in the number of stickers between Charlie and Bryan
= 10 u - 4 u
= 6 u
Answer(s): (a) 1; (b) 4; (c) 19; (d) 6
