Textbook 6.2 - 5a, 5d, 9, 12
Share 3/5 between 2 groups. First thing you do is change the whole number (2) and turn it into an improper fraction (2/1). You try and find the reciprocal which is 1/2 and you multiply it to get 1 whole. Now, what you do to the bottom, you must do to the top. So 3/5 multiply by 1/2 equals 3/10. Now if you divide 3/10 and 1, it would still be 3/10.

12. It takes 4/5 of a roll of ribbon to wrap six packages. What fraction of a roll does it take to wrap three packages?
