To find how many times \( 5 \cdot 10^5 \) is as large as \( 1 \cdot 10^5 \), you can divide \( 5 \cdot 10^5 \) by \( 1 \cdot 10^5 \):
\[ \frac{5 \cdot 10^5}{1 \cdot 10^5} \]
Now, you can simplify this:
\[ = \frac{5}{1} \cdot \frac{10^5}{10^5} \] \[ = 5 \cdot 1 \] \[ = 5 \]
So, \( 5 \cdot 10^5 \) is 5 times as large as \( 1 \cdot 10^5 \).
