<h3>15.</h3>
This is an example of a problem in which cross-multiplying introduces the need for an extra step: divide by 3. Had we simply multiplied by the denominator of the x-term, we would have been finished in one step:
x = 6(2/3) = 4
That is, rather than multiplying by the <em>product of the denominators</em>, sometimes the problem can be solved more easily if you multiply by their <em>least common multiple</em>.

Answer: Median
You can't use the mode in here, since there are no repeated numbers. But You can use mean and median. If you use the mean, you will get 57. If you use the median, you will get 75.5. This means that the median will give you the best grade.
Explanation:
Mode: The most repeated number.
Median: The Middle number of statistics.
Mean: The average of all numbers.
