6th grade 15 13 28
7th grade 30 29 59
8th grade 13 17 30
Total 58 59 117

What percent of the 8th graders don't have a pet? Round your answer to the nearest whole number percent.

Answer 1

To find the percentage of 8th graders who don't have a pet, we need to divide the number of 8th graders who don't have a pet by the total number of 8th graders, and then multiply by 100 to convert it to a percentage.

From the data, we see that:
- The number of 8th graders with pets is 13.
- The number of 8th graders without pets is 17.
- The total number of 8th graders is 30.

Now, we can calculate the percentage of 8th graders without pets:

\[
\text{Percentage} = \left( \frac{\text{No Pets}}{\text{Total}} \right) \times 100
\]

\[
\text{Percentage} = \left( \frac{17}{30} \right) \times 100
\]

Calculating this:

\[
\text{Percentage} = \left( 0.5667 \right) \times 100 \approx 56.67
\]

Rounding to the nearest whole number gives us:

\[
\text{Percentage} \approx 57\%
\]

Therefore, approximately **57%** of the 8th graders don't have a pet.
