After |
7 x 3 = 21 u |
3 x 3 = 9 u |
(a)
Change percentage into units.
25% =
25100 =
14 Fraction of the stickers that Bryan has at first =
14 30% =
30100 =
310 Fraction of the stickers that Bryan has in the end =
310 The number of stickers that Bryan has remained unchanged.
LCM of 3 and 7 = 21
Number of stickers that Bryan has at first = 7 u
(b)
Change in the number of stickers that Bryan has
= 9 u - 7 u
= 2 u
(c)
Number of stickers that Adam has = 21 u
(d)
Number of stickers that Adam has in the end = 21 u
Answer(s): (a) 7; (b) 2; (c) 21; (d) 21
