The total number of stickers that Jaslyn had at first is repeated. Make the total number of stickers at first the same. LCM 2 and 6 is 6.
Number of brown stickers that Jaslyn gave away
= 50% x 1 u
=
50100 x 1 u
= 0.5 u
1.5 u - 154 = 5 u
5 u - 1.5 u = 154
3.5 u = 154
1 u = 154 ÷ 3.5 = 44
Number of stickers that Jaslyn gave away
= 5 u
= 5 x 44
= 220
Answer(s): 220
