- Number of stickers that Charlie has = _____ u
- Total number of stickers = _____ u
- Difference in the number of stickers between Adam and Charlie = _____ u
(a)

15 u |
25 u |
12 u |
(b)
LCM of 3 and 5 = 15
Number of stickers that Charlie has = 12 u
(c)
Total number of stickers that the children have
= 15 u + 25 u + 12 u
= 52 u
(d)
Difference in the number of stickers between Adam and Charlie
= 25 u - 12 u
= 13 u
Answer(s): (a) 1; (b) 12; (c) 52; (d) 13
