After |
2 x 9 = 18 u |
3 x 9 = 27 u |
(a)
Change percentage into units.
55% =
55100 =
1120 Fraction of the stickers that Bryan has at first =
1120 60% =
60100 =
35 Fraction of the stickers that Bryan has in the end =
35 The number of stickers that Bryan has remained unchanged.
LCM of 9 and 2 = 18
Number of stickers that Bryan has at first = 22 u
(b)
Change in the number of stickers that Bryan has
= 27 u - 22 u
= 5 u
(c)
Number of stickers that Adam has = 18 u
(d)
Number of stickers that Adam has in the end = 18 u
Answer(s): (a) 22; (b) 5; (c) 18; (d) 18
