To find out how many pages do not have advertisements in Streamliner magazine, we can follow these steps:

1. **Calculate the number of pages with advertisements**:
   - The magazine has a total of 192 pages.
   - The fraction of pages with advertisements is 0.7.

We can calculate the number of pages with advertisements using the formula:
   $$
   \text{Pages with advertisements} = \text{Total pages} \times \text{Fraction of pages with advertisements}
   $$

2. **Calculate the number of pages without advertisements**:
   - We can find the number of pages without advertisements by subtracting the number of pages with advertisements from the total number of pages.

Let's perform the calculations step by step.

### Step 1: Calculate the number of pages with advertisements
$$
\text{Pages with advertisements} = 192 \times 0.7
$$

### Step 2: Calculate the number of pages without advertisements
$$
\text{Pages without advertisements} = 192 - \text{Pages with advertisements}
$$

Now, let's calculate these values.

First, we calculate the pages with advertisements:
$$
192 \times 0.7 = 134.4
$$

Since the number of pages must be a whole number, we round this to 134 pages with advertisements.

Now, we calculate the pages without advertisements:
$$
192 - 134 = 58
$$

Thus, the number of pages that do not have advertisements is **58 pages**.
There are 58 pages without advertisements.
