Answer:
Explanation:
If the board is 5/8 of a yard, then it is 5/8 of 36 inches (a yard is 36 inches).
5/8 * 36 = 22.5 inches.
Frank now cut's 3/5 of the length of the board. So he is going to cut off 3/5 of 22.5 inches.
(3/5) * 22.5 = 67.5 / 5 = 13.5 inches.
You don't specify what the units should be. I translate this into yards, but I think if you want something else, leave a comment.
13.5 /36 = 0.375 = 3/8 of a yard.
