+ ? |
After |
9 x 4 = 36 u |
11 x 4 = 44 u |
(a)
Change percentage into units.
20% =
20100 =
15 Fraction of the stickers that Bryan has at first =
15 55% =
55100 =
1120 Fraction of the stickers that Bryan has in the end =
1120 The number of stickers that Bryan has remained unchanged.
LCM of 4 and 9 = 36
Number of stickers that Bryan has at first = 9 u
(b)
Change in the number of stickers that Bryan has
= 44 u - 9 u
= 35 u
(c)
Number of stickers that Adam has = 36 u
(d)
Number of stickers that Adam has in the end = 36 u
Answer(s): (a) 9; (b) 35; (c) 36; (d) 36
