How many 3 wires can be cut from a spool of wire that is 100 inches long?
 wires can be cut from a spool of wire that is 100 inches long?
How many inches will be left over?
Number of pieces of wires = length of spool of wire ÷ length of each piece of wire.
Number of pieces = 100 ÷ 3 = 100 ÷
 = 100 ÷ 
That gives 
Simplifying gives  =
 = 
This is equivalent to 26 pieces
 pieces
So 26 pieces of wires can be cut from a spool and  of a piece will be left over.
 of a piece will be left over.
