After |
4 x 9 = 36 u |
1 x 9 = 9 u |
(a)
Change percentage into units.
10% =
10100 =
110 Fraction of the stickers that Bryan has at first =
110 20% =
20100 =
15 Fraction of the stickers that Bryan has in the end =
15 The number of stickers that Bryan has remained unchanged.
LCM of 9 and 4 = 36
Number of stickers that Bryan has at first = 4 u
(b)
Change in the number of stickers that Bryan has
= 9 u - 4 u
= 5 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) 4; (b) 5; (c) 36; (d) 36
