Sarah had 120 purple stickers and 56 grey stickers. Sarah gave away 30% of her purple stickers and 50% of her grey stickers. What percentage of her stickers left was grey?
Percentage of purple stickers left
= 100% - 30%
= 70%

Percentage of grey stickers left
= 100% - 50%
= 50%
Number of grey stickers left
= 50% x 56
=
50100 x 56
= 28
Total number of stickers left
= 84 + 28
= 112
Percentage of stickers left that are grey
