Aplumber has a cooper pipe 0,9 meter long he cuts the the pipe into 4 equal pieces find the length of each piece in meters. round your answer to the nearest tenth of a meter

Assuming you meant 0.9 meters
You need to find the .9 of a meter first, so 90% of a meter. You do this by finding how many inches a meter (3 feet) is, which would be 36. 36/10= 3.6 inches, and 3.6*9= 32.4. 

Now, to find the lengths of the pieces, divide 32.4 by 4:

32.4/4= 8.1 inches.

Hope this helps!
