Solution
To find the percentage of 7th graders who have a pet, you need to follow these steps:
-
First, find the total number of 7th graders. This is done by adding the number of 7th graders who have pets to the number of 7th graders who do not have pets. According to the table, there are 24 7th graders with pets and 13 7th graders without pets. So, the total number of 7th graders is 24 + 13 = 37.
-
Next, find the number of 7th graders who have pets. According to the table, this number is 24.
-
Then, calculate the percentage of 7th graders who have pets. This is done by dividing the number of 7th graders who have pets by the total number of 7th graders, and then multiplying the result by 100 to convert it to a percentage. So, the percentage of 7th graders who have pets is (24 / 37) * 100 = 64.86%.
-
Finally, round this percentage to the nearest whole number. So, the final answer is approximately 65%. Therefore, about 65% of the 7th graders have a pet.
