The relative frequency of the percent of 7th graders who prefer mountains can be found by dividing the number of 7th graders who prefer mountains (40) by the total number of students (310) and then multiplying by 100.
(40/310) * 100 = 12.9
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is approximately 12.9%.
