Adam has 25% of the total stickers.
If Adam receives extra stickers,
his number of stickers increases to 35%.

- Change in the number of stickers that Adam has = _____ u
- Number of stickers that Bryan has at first = _____ u
- Number of stickers that Bryan has in the end = _____ u

Before |
3 x 13 = 39 u |
1 x 13 = 13 u |
Change |
No change |
+ ? |
After |
13 x 3 = 39 u |
7 x 3 = 21 u |
(a)
Change percentage into units.
25% =
25100 =
14 Fraction of the stickers that Adam has at first =
14 35% =
35100 =
720 Fraction of the stickers that Adam has in the end =
720 The number of stickers that Adam has remained unchanged.
LCM of 3 and 13 = 39
Number of stickers that Adam has at first = 13 u
(b)
Change in the number of stickers that Adam has
= 21 u - 13 u
= 8 u
(c)
Number of stickers that Bryan has = 39 u
(d)
Number of stickers that Bryan has in the end = 39 u
Answer(s): (a) 13; (b) 8; (c) 39; (d) 39
