Answer:

4.  35 times larger

Step-by-step explanation:

<em>Doing Question #4 Only</em>

<em />

4.

Before we see this problem's solution. Lets get a background.

Suppose something has an area of "A" sq. meters.

and

Suppose another land has an area of "B" sq. meters.

and suppose A > B

If we want to know how many times A is larger than B, we simply have to divide the larger one (A) by the smaller one (B).

Now, onto our question:

We want to know how many times larger the national is than state park. So we divide the area of national by the area of state. That would be:

\frac{7*10^8}{2*10^7}

<em>Since the numbers are in scientific notation, we look at the rule below on how to divide scientific notation numbers:</em>

<em>\frac{a*10^b}{c*10^d}=(\frac{a}{c})*10^{b-d}</em>

<em />

<em>Now, we apply the rule:</em>

<em>\frac{7*10^8}{2*10^7}\\=\frac{7}{2}*10^{8-7}\\=3.5*10^1\\=3.5*10\\=35</em>

<em />

So, the national park is 35 times larger than the state park.
