Decimal charterer too many decimal spaces

I am getting too many decimal spaces, I only want to see 2 decimal spaces, example (0.67) and (0.04)

This is code.

Thank you

//Linear FT Stack =Q2/12
                Decimal Q = Convert.ToInt32(rows.Cells[16].Value ?? 0);
                var C = 12;
                Decimal W = Q / C;
                rows.Cells[22].Value = W;

//Raw Linear Ft Day =(V2*W2)/U2 
                int V21 = Convert.ToInt32(rows.Cells[21].Value ?? 0);
                var W22 = Convert.ToDecimal(rows.Cells[22].Value ?? 0);
                int U20 = Convert.ToInt32(rows.Cells[20].Value ?? 0);
                var X = V21 == 0 ? 0 : V21 * W22 / U20;
                rows.Cells[23].Value = X;

This is my result with above code.
