\( -0.2+\frac{7}{10}=\square \) Enter the answer as an exact decimal or simplified fraction.

To solve the expression \( -0.2 + \frac{7}{10} \), we first convert \(-0.2\) into a fraction. \(-0.2\) is equivalent to \(-\frac{2}{10}\). Now we have: \[ -\frac{2}{10} + \frac{7}{10} \] Since the denominators are the same, we can combine the numerators: \[ \frac{-2 + 7}{10} = \frac{5}{10} \] Now, simplifying \(\frac{5}{10}\) gives us \(\frac{1}{2}\) or \(0.5\) as a decimal. Therefore, the answer is: \(\frac{1}{2}\) or \(0.5\)
