Adam has 40% of the total stickers.
If Adam receives extra stickers,
his number of stickers increases to 45%.

- 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 11 = 33 u |
2 x 11 = 22 u |

No change |
+ ? |
After |
11 x 3 = 33 u |
9 x 3 = 27 u |
(a)
Change percentage into units.
40% =
40100 =
25 Fraction of the stickers that Adam has at first =
25 45% =
45100 =
920 Fraction of the stickers that Adam has in the end =
920 The number of stickers that Adam has remained unchanged.
LCM of 3 and 11 = 33
Number of stickers that Adam has at first = 22 u
(b)
Change in the number of stickers that Adam has
= 27 u - 22 u
= 5 u
(c)
Number of stickers that Bryan has = 33 u
(d)
Number of stickers that Bryan has in the end = 33 u
Answer(s): (a) 22; (b) 5; (c) 33; (d) 33
