Explanation:

Step1: Calculate total adults

Add the number of adults for each number of children. From the bar - graph, the number of adults with 0 children is 4, with 1 child is 8, with 2 children is 4, with 3 children is 1, and with 5 children is 2. So the total number of adults questioned is $4 + 8+4 + 1+2$.
$4 + 8+4 + 1+2=19$

Step2: Calculate percentage of adults with 5 children

The formula for percentage is $\text{Percentage}=\frac{\text{Number of adults with 5 children}}{\text{Total number of adults}}\times100\%$. We know the number of adults with 5 children is 2 and the total number of adults is 19.
$\text{Percentage}=\frac{2}{19}\times100\% \approx 10.53\%$

Answer:

19
10.53%
