If Adam receives extra stickers,
his number of stickers increases to 45%.

Before |
4 x 11 = 44 u |
1 x 11 = 11 u |

No change |
+ ? |
After |
11 x 4 = 44 u |
9 x 4 = 36 u |
(a)
Change percentage into units.
20% =
20100 =
15 Fraction of the stickers that Adam has at first =
15 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 4 and 11 = 44
Number of stickers that Adam has at first = 11 u
(b)
Change in the number of stickers that Adam has
= 36 u - 11 u
= 25 u
(c)
Number of stickers that Bryan has = 44 u
(d)
Number of stickers that Bryan has in the end = 44 u
Answer(s): (a) 11; (b) 25; (c) 44; (d) 44
