After |
3 x 7 = 21 u |
17 x 7 = 119 u |
(a)
Change percentage into units.
65% =
65100 =
1320 Fraction of the stickers that Bryan has at first =
1320 85% =
85100 =
1720 Fraction of the stickers that Bryan has in the end =
1720 The number of stickers that Bryan has remained unchanged.
LCM of 7 and 3 = 21
Number of stickers that Bryan has at first = 39 u
(b)
Change in the number of stickers that Bryan has
= 119 u - 39 u
= 80 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) 39; (b) 80; (c) 21; (d) 21
