What are the mean, median, and mode of the following data set? 3/4 2/5 1/10 3/4 1/4

The fractions in order are 1/10, 1/4, 2/5, 3/4, and 3/4, so the middle value—and therefore the median—is 2/5. The sum is 9/4, and dividing by 5 gives a mean of 9/20. Since 3/4 appears twice while every other value appears once, the mode is 3/4. This matches choice C.
