Answer
Explanation:
Step1: Find total 6th - graders
Add the number of 6th - graders with pets and without pets. $20 + 26=46$.
Step2: Calculate the percentage of 6th - graders with pets
Use the formula $\text{Percentage}=\frac{\text{Number of 6th - graders with pets}}{\text{Total number of 6th - graders}}\times100%$. So, $\frac{20}{46}\times 100%$. $\frac{20}{46}\times100%=\frac{2000}{46}% \approx 43.5%$.
Answer:
$43.5$
