To determine the relative frequency of the percent of 7th graders who prefer mountains, you need to divide the number of 7th graders who prefer mountains by the total number of 7th graders and then multiply by 100 to convert it to a percentage.
Number of 7th graders who prefer mountains: 40
Total number of 7th graders: 110
Relative frequency = (40 / 110) x 100 = 36.4%
Therefore, the relative frequency of the percent of 7th graders who prefer mountains is 36.4%.
