Example Question #381 : Numbers And Operations

Multiply the following:

Possible Answers:

Correct answer:

Explanation:

To multiply fractions, we will multiply the numerators together, then we will multiply the denominators together.  Note that we do NOT need to find a common denominator. 

So, in the problem 

we first need to write 25 as a fraction.  We know that whole numbers can be written as fractions over 1.  So, we get

Now, we can simplify before we multiply to make things easier.  The 5 and the 25 can both be divided by 5.  So, we get

Now, we will multiply straight across.  We get
