If Adam receives extra stickers,
his number of stickers increases to 60%.

Before |
11 x 2 = 22 u |
9 x 2 = 18 u |

No change |
+ ? |
After |
2 x 11 = 22 u |
3 x 11 = 33 u |
(a)
Change percentage into units.
45% =
45100 =
920 Fraction of the stickers that Adam has at first =
920 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 11 and 2 = 22
Number of stickers that Adam has at first = 18 u
(b)
Change in the number of stickers that Adam has
= 33 u - 18 u
= 15 u
(c)
Number of stickers that Bryan has = 22 u
(d)
Number of stickers that Bryan has in the end = 22 u
Answer(s): (a) 18; (b) 15; (c) 22; (d) 22
