Answer:
21/50
Explanation:
Given that Jackson's sweets from last Halloween from last year was 42% chocolate, we can assume he had a total of 100 sweets.
Out of 100 sweets, 42 pieces are chocolate, so:
42/100
When simplifying this fraction into its simplest form, the most you can do is divide the numerator(top) and denominator(bottom) by 2.
Your result would be 21/50
