A 42-meter length of wiring is cut into pieces that measure 3.2 meters each. Into how many pieces is the wiring cut?

13pieces

Step-by-step explanation:

Length of the wire = 42 meter

Length of piece of wire = 3.2 meter

No. of pieces = 42/3.2

= 42*10 / 3.2*10

= 420/32.0

= 420/32

= 13.125

No of pieces = 13

0.125m of wire is remaining
