(a)
Change percentage into units.
65% =
65100 =
1320Fraction of the stickers that Adam has at first =
1320 Number of stickers that Adam has at first = 13 u
(b)
Change in the number of stickers that Adam has

=
55100 x 13 u
= 0.55 x 13 u
= 7.15 u
(c)
Number of stickers that Adam has in the end
= 13 u + 7.15 u
= 20.15 u
(d)
