Answer:
D) 80%
Explanation:
To find the fraction of women surveyed who prefer salads, we need to know something about how many were surveyed, and how many of those preferred salads.
For this purpose, we can effectively ignore the percent signs in the table, and consider that it represent 100 people surveyed.
__
Of the 100 people surveyed, 40 were women. Of the 40 women, 32 preferred salads. That is, 32/40 = 8/10 = 80% of the women surveyed preferred salads.
_____
Additional comment
When dealing with percentages, one must always keep in mind the base the percentage is referring to. For all of the numbers in the table, the base is the total number of participants in the survey.
For the percentage that is the answer to the question, the base is the number of women surveyed (or something proportional to that number).
