The Answer would be 20/6 but that can reduced down to back down to 10/3. To multiply a fraction by a whole number, know that a while number like four is always over 1 so it would 5/6 x 4/1. To multiplay fractions, you multiply the top numbers ( 5 x 4 ) and then your bottom numbers ( 6 x 1 ) which gives you your answer: 20/6 which you might want to reduce if possible which you can.
