Gem had 112 brown coins and 60 black coins. Gem gave away 25% of her brown coins and 65% of her black coins. What percentage of her coins left was black?
Percentage of brown coins left
= 100% - 25%
= 75%
Number of brown coins left
= 75% x 112
= 75100 x 112
= 84
Percentage of black coins left
= 100% - 65%
= 35%
Number of black coins left
= 35% x 60
=
35100 x 60
= 21
Total number of coins left
= 84 + 21
= 105
Percentage of coins left that are black
=
21105 x 100%
= 20%
Answer(s): 20%
