How many 3
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.

That gives 
Simplifying gives
= 
This is equivalent to 26
pieces
So 26 pieces of wires can be cut from a spool and
of a piece will be left over.
