5*15.75=78.75
128-2=126
126-78.75=47.25
47.25/7=6.75
The length of each piece of the seven pieces would be 6.75 inches.

The length of each of the seven pieces is 6.75 inches

<h3>Further explanation </h3>

Jim Nasium is building a tree house for his two daughters. He cut 12 pieces of wood from a board that is 128 inches long. He cuts 5 pieces that measure 15.75 inches each, and 7 pieces evenly cut from what is left.

Let we solve this:

He cuts 5 pieces that measure 15.75 inches each, therefore

15.75 inches* 5 pieces=  78.75 inches

He cut 12 pieces of wood from a board that is 128 inches long, so

128 inches - 78.75 inches= 49.25 inches

Jim calculates that due to the width of his cutting blade he will lose a total of 2 inches of wood after making all of the cuts, so

49.25 inches - 2 inches = 47.25 inches

He cuts 5 pieces that measure 15.75 inches each, and 7 pieces evenly cut from what is left, therefore

\frac{ 47.25 inches}{7}  = 6.75 inches

Therefore, the length of each of the seven pieces is 6.75 inches
