Answer 1

To answer your questions regarding the families who own pets in Lincoln Valley neighborhood, let's go through each part step by step.

### Part (a): Create a Double Number Line
A double number line can be helpful in visualizing the relationship between the number of families and the percentage of families who own pets. Here is a simple representation you can visualize:

```
Families: 0 60 100 200
|----------|---------|--------|
Percentage: 0% 30% 50% 100%
```

In this representation:
- 60 families out of 200 families own pets.
- At 200 families, 100% is represented.
- To find the percentage, we can identify what percentage corresponds to 60 families.

### Part (b): What Percentage of the Families Own Pets?
To find the percentage of families that own pets, we can use the following formula:

\[
\text{Percentage} = \left( \frac{\text{Number of families with pets}}{\text{Total number of families}} \right) \times 100
\]

Substituting values:

\[
\text{Percentage} = \left( \frac{60}{200} \right) \times 100
\]

\[
\text{Percentage} = 0.3 \times 100 = 30\%
\]

Therefore, \(30\%\) of the families in the Lincoln Valley neighborhood own pets.
