### Example Question #1 : How To Multiply Fractions

**Possible Answers:**

**Correct answer:**

When multiplying fractions you simply multiply the numerators to find the numerator of the product, and multiply the denominators to find the denominator of the product.

So, our product is .

Since both of these numbers are divisible by three, we simplify.

Our final answer is .

### Example Question #3 : How To Multiply Fractions

**Possible Answers:**

**Correct answer:**

When dealing with problems that involve fractions and whole numbers, first convert your whole number into a fraction. You can easily do this by putting the whole number over 1.

When multiplying, multiply the numerators by each other and the denominators by each other.

Always reduce a fraction when possible. In this case, the numerator and denominator of are both divisible by 4. So, it reduces to 9.
