If you would like to know how long will each piece of licorice be, you can calculate this using the following steps:
the length of the piece of licorice ... 2/3 yard
10 equal size pieces
2/3 yard / 10 pieces = 2/3 / 10 = 2/3 * 1/10 = 1/15 yard
The correct result would be: Each piece would be 1/15 yard long.
