Lucy had 120 red buttons and 52 brown buttons. Lucy gave away 35% of her red buttons and 50% of her brown buttons. What percentage of her buttons left was brown?
Percentage of red buttons left
= 100% - 35%
= 65%
Number of red buttons left
= 65% x 120
= 65100 x 120
= 78
Percentage of brown buttons left
= 100% - 50%
= 50%
Number of brown buttons left
= 50% x 52
=
50100 x 52
= 26
Total number of buttons left
= 78 + 26
= 104
Percentage of buttons left that are brown
