To determine the relative frequency of the percent of 7th graders who prefer mountains, we need to divide the number of 7th graders who prefer mountains by the total number of students:
40 / 310 = 0.129
To convert this to a percentage, we multiply by 100:
0.129 * 100 = 12.9%
Rounded to the nearest tenth, the relative frequency of the percent of 7th graders who prefer mountains is 12.9%.
Therefore, the closest answer choice is:
26.7%
