Asurvey determined that 7/18 of the seventh grade students at mills middle school preferred round chocolate candies to hard candy. when jennifer duplicated the survey, 1/9 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. 8/27 b. 7/162 c. 5/ 18 d. 1/2

The correct answer is C) 5/18

Step-by-step 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.

7/18 - 1/9

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

7/18 - 2/18 = 5/18

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
