3/4 = 75 % of the data is greater than the first quartile in a box-and-whisker plot.

Step-by-step explanation:

75 % of the data is greater than the first quartile in a box-and-whisker plot.

The first quartile denoted by Q1 is the median of the lower half of the data set.

This means that 25% of the values lie in the first quartile and 75 % of the values lie above the first quartile.

In the box and whisker plot the longer box indicates the interquartile range whereas the sides represent the 1st and 3rd quartile. The first quartile is the region where the values start and increase to the interquartile range.

75 % means = 75/100 or 0.75 or 3/4

75/100 = 15/20 = 3/4
