Answer: 13/20
Explanation:
This question is based around conversions; you should know how to convert between percentages and fractions.
The question says that Lakisha drank 35% of the water contents. This means that she did not drink 65% (100% - 35% = 65%)
Now here is where the conversion comes in.
65% as a fraction is 65/100.
However, this isn't an option, so you have to simplify the fraction by dividing by 5.
65 / 5 = 13
100 / 5 = 20
Therefore, the answer is 13/20
Hope this helps :)
