What you are to do is the mixed numeral is converted to a improper fraction. To do this just simply multiply the denominator with the whole number then add that with the numerator. With that number you end up with will be the numerator over whatever the denominator was. Then you can multiply the fractions.
(I'm not a good explainer but i hoped i helped a bit)
