To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to divide the number of 7th grade students who prefer mountains (40) by the total number of students (310) and then multiply by 100 to get the percentage.
(40 / 310) * 100 = 12.9%
So, the relative frequency of the percent of 7th graders who prefer mountains is 12.9%, rounded to the nearest tenth.
