Fill in the blanks.
2 boys, Bryan and Adam, share some stickers.
Adam has 25% of the total stickers.
If Adam receives extra stickers,
his number of stickers increases to 60%.
- Number of stickers that Adam has at first = _____ u
- 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 2 = 6 u |
1 x 2 = 2 u |

No change |
+ ? |
After |
2 x 3 = 6 u |
3 x 3 = 9 u |
(a)
Change percentage into units.
25% =
25100 =
14 Fraction of the stickers that Adam has at first =
14 60% =
60100 =
35 Fraction of the stickers that Adam has in the end =
35 The number of stickers that Adam has remained unchanged.
LCM of 3 and 2 = 6
Number of stickers that Adam has at first = 2 u
(b)
Change in the number of stickers that Adam has
= 9 u - 2 u
= 7 u
(c)
Number of stickers that Bryan has = 6 u
(d)
Number of stickers that Bryan has in the end = 6 u
Answer(s): (a) 2; (b) 7; (c) 6; (d) 6
