Question

A survey determined that 5/18 of the seventh grade students at Mills Middle School preferred round chocolate candies to hard candy. When Jennifer duplicated the survey, 1/6 of the students changed their preference from chocolate candy to hard candy. What fraction of the students in the second survey preferred round chocolate candy? A. 4/9 B. 1/9 C. 5/ 108 D. 1/4

Answer 1

The correct answer is B) 1/9

Explanation:

In order to find this answer, you need to take the fraction that answered it on the first try and subtract the number that changed their mind.

5/18 - 1/6

In order to complete this operation, you need to give them common denominators.

5/18 - 3/18 = 2/18

And we can simplify that answer.

2/18 = 1/9
