PLEASE HELP THANK YOU

An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 2 1/5 yards of paper for one box and 9/10 yards of paper for the other box. The paper must be cut into pieces that are 1/10 yard long. How many pieces will the student cut to use for the gift boxes?


The student will cut ____ pieces to use for the gift boxes.


If you can answer this thank you also please show how you did it so I can do it by myself :)
