Answer
$-2\dfrac{3}{10}$
Work Step by Step
Write the mixed number in improper fraction form to obtain:
$=-\dfrac{4[}{5} + \left(-\dfrac{2(1)+1}{2}\right)
\\=-\dfrac{4}{5} + \left(-\dfrac{3}{2}\right)$
Make the fractions similar using their LCD, which is $10$. to obtain:
$=-\dfrac{4(2)}{5(2)}+\left(-\dfrac{3(5)}{2(5)}\right)
\\=-\dfrac{8}{10} + \dfrac{-15}{10}
\\=\dfrac{-8+(-15)}{10}
\\=\dfrac{-23}{10}
\\=-2\dfrac{3}{10}$
