A group of adults were asked how many children they have in their families. The bar graph below shows the number of adults who indicated each number of children. How many adults were questioned?
What percentage of the adults questioned had 1 children?

To solve this problem, let's break down the information from the bar graph.

### Step 1: Count the Total Number of Adults
The bar graph displays the number of adults for each count of children. By adding these values together, we can find the total number of adults questioned.

From the bar graph:
- **0 children**: 6 adults
- **1 child**: 8 adults
- **2 children**: 5 adults
- **3 children**: 7 adults
- **4 children**: 4 adults

Adding these:
\[
6 + 8 + 5 + 7 + 4 = 30
\]
So, **30 adults were questioned**.

### Step 2: Calculate the Percentage of Adults with 1 Child
Now, we need to find the percentage of adults who have exactly 1 child.

The formula for percentage is:
\[
\text{Percentage} = \left( \frac{\text{Number of adults with 1 child}}{\text{Total number of adults}} \right) \times 100
\]

Plugging in the values:
\[
\text{Percentage} = \left( \frac{8}{30} \right) \times 100 = \frac{800}{30} \approx 26.67\%
\]

Thus, **26.67% of the adults questioned had 1 child**.
