5/9 of 54 are the ones which have chocolate, so we need to multiply the fraction by 54
5/9 * 54 = 30
Since 30 pieces of candy have chocolate, then 24 don't have it. 2/3 of the last number are the ones which have gum, multiply 2/3 by 24 to get the answer:
2/3 * 24 = 16.
The answer is: 16 pieces of candy have gum
