Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.
The length of the rope = 21 feet
the length of each strip = [tex] \frac{1}{5} [/tex]
We need to cut the rope 21 feet into [tex] \frac{1}{5} [/tex] strips
To find the number of strips we divide 21 feet by the length of the strip
[tex] \frac{21}{\frac{1}{5}} [/tex] = [tex] 21 * \frac{5}{1} [/tex] = 105
105 strips can Bruce cut from his rope.
