Question

How many 2.4 m lengths of wire can be cut
from a roll 156.4 m long?
How much wire is wasted?

Answer 1

Answer:

65 and 0.4m

Step-by-step explanation:

Total length of wire: 156.4 m

Pieces to be cut: 2.4 m

Number of pieces: 156.4/2.4= 65 full pieces

65*2.4=156 m used and 156.4-156=0.4 m wasted

Answer 2

Answer:

Length of wire to be cut = 2.4 m

Total length of the wire =156.4m

Number of wires to be cutted =156.4/2.4

                                                   =65.16 pieces

Taking as whole if we divide only 156 by 2.4 we can find it as 65 pieces of wire..

Therefore the number of wires cutted from the roll is 65 pieces..

If there are 65 pieces of wire

Then 65*2.4=156m

Which means 156 m of wire only have been used..

If only 156 m wire only is cutted means we can better understand this as 0.4 m are wasted..

Therefore the length of the wire wasted is 0.4 m..
