To multiply fractions, we multiply across the tops, multiply across the bottoms, and then reduce. If you are multiplying a fraction by an integer, you can write the integer value over one to make it look like a fraction- this will help you keep track of what is in the top versus bottom of the fraction. Alternatively, you could reduce the fractions first, even reducing tops and bottoms from different fractions, and then multiply across the tops and bottoms of the reduced form.
