<h3>Answer: Choice E</h3>

======================================================

Explanation:

Think of 25 as 25/1 and 5 as 5/1

Choice E is really saying $\frac{25}{1} \div \frac{5}{1}$ which becomes $\frac{25}{1} \times \frac{1}{5}$ . Note the second fraction flips and we change to a multiplication sign.

------------

Or you could think of it like this:

$25 \times \frac{1}{5} = \frac{25}{1} \times \frac{1}{5} = \frac{25*1}{1*5} = \frac{25}{5} = 25 \div 5$

to help see why the answer is E.
