a piece of wire 3.5m long was cut into lengths each measuring 0.05m long.Calculate the number of pieces obtained.

3.5 m/0.05m = ?

70 70m

To calculate the number of pieces obtained, you need to divide the total length of the wire by the length of each piece.

In this case, the total length of the wire is given as 3.5 meters, and the length of each piece is 0.05 meters.

So, to find the number of pieces, you can use the formula:

Number of pieces = Total length of the wire / Length of each piece

Plugging in the values:

Number of pieces = 3.5 meters / 0.05 meters

Dividing, we get:

Number of pieces = 70

Therefore, you would obtain 70 pieces from the wire.
