After |
3 x 11 = 33 u |
7 x 11 = 77 u |
(a)
Change percentage into units.
45% =
45100 =
920 Fraction of the stickers that Bryan has at first =
920 70% =
70100 =
710 Fraction of the stickers that Bryan has in the end =
710 The number of stickers that Bryan has remained unchanged.
LCM of 11 and 3 = 33
Number of stickers that Bryan has at first = 27 u
(b)
Change in the number of stickers that Bryan has
= 77 u - 27 u
= 50 u
(c)
Number of stickers that Adam has = 33 u
(d)
Number of stickers that Adam has in the end = 33 u
Answer(s): (a) 27; (b) 50; (c) 33; (d) 33
