this is the trouble: 1/3x(-2x3.15)
my nephew say is -2.33 because we need to rounded the -6.3 to -7. The prof he's ok with the -7 but he never give the answer to how to get the -7, for me the answer is -2.09999996 (rounded to -2.1)... Why is not the same result?

thank's a lot

The exact answer is 0.267. I'm sorry but I don't have time to explain.

$$\frac{1}{3}\times(-2\times3.15)=\frac{1}{3}\times(-6.3)=-\frac{6.3}{3}=-2.1$$
