If Adam receives extra stickers,
his number of stickers increases to 65%.

- 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 7 = 21 u |
1 x 7 = 7 u |

No change |
+ ? |
After |
7 x 3 = 21 u |
13 x 3 = 39 u |
(a)
Change percentage into units.
25% =
25100 =
14 Fraction of the stickers that Adam has at first =
14 65% =
65100 =
1320 Fraction of the stickers that Adam has in the end =
1320 The number of stickers that Adam has remained unchanged.
LCM of 3 and 7 = 21
Number of stickers that Adam has at first = 7 u
(b)
Change in the number of stickers that Adam has
= 39 u - 7 u
= 32 u
(c)
Number of stickers that Bryan has = 21 u
(d)
Number of stickers that Bryan has in the end = 21 u
Answer(s): (a) 7; (b) 32; (c) 21; (d) 21
