No change |
+ ? |
After |
11 x 3 = 33 u |
9 x 3 = 27 u |
(a)
Change percentage into units.
25% =
25100 =
14 Fraction of the stickers that Bryan has at first =
14 45% =
45100 =
920 Fraction of the stickers that Bryan has in the end =
920 The number of stickers that Bryan has remained unchanged.
LCM of 3 and 11 = 33
Number of stickers that Bryan has at first = 11 u
(b)
Change in the number of stickers that Bryan has
= 27 u - 11 u
= 16 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) 11; (b) 16; (c) 33; (d) 33
