Three odd-shaped blocks of chocolate have the following masses and center-of-mass coordinates:

(1) 0.310 kg, ( 0.200 m, 0.310 m);

(2) 0.410 kg, ( 0.110 m, -0.380 m);

(3) 0.200 kg, ( -0.280 m, 0.610 m).

Find the x coordinate of the center of mass of the system of three chocolate blocks.

3. The attempt at a solution

This is how I commenced,

I took (mass1*x1+mass2*x2+mass3*x3)/(m1+m2+m3) and got .051

this should be right but I got it wrong. I then redid the calculation and this time I got .05

not that much difference, I only got one try left, and don't think this is right because they are so close together.

I did the y the same way and got it right. :S

Please and thank you.
