If you have a rope that is 25 1/2 feet long and you want to cut it into 6 pieces that are equal in length, and you want to know how long will each piece be, you can calculate this using the following steps:
25 1/2 feet = 51/2 feet
25 1/2 / 6 = 51/2 / 6 = 51/2 * 1/6 = 51/12 = 17/4 = 4 1/4 feet
Result: Each piece will be 4 1/4 feet long.
