Diana had 56 black stickers and 40 red stickers. Diana gave away 25% of her black stickers and 55% of her red stickers. What percentage of her stickers left was red?
Percentage of black stickers left
= 100% - 25%
= 75%
Number of black stickers left
= 75% x 56
= 75100 x 56
= 42
Percentage of red stickers left
= 100% - 55%
= 45%
Number of red stickers left
= 45% x 40
=
45100 x 40
= 18
Total number of stickers left
= 42 + 18
= 60
Percentage of stickers left that are red
