Question

(-1/3)+(+6/5-4/8)+(-2

Answer 1

$\displaystyle \left(-\frac{1}{3}\right)+\left( \frac{6}{5}- \frac{4}{8}\right)+(-2)= \left(-\frac{1}{3}\right)+\left( \frac{48-20}{40}\right)+(-2) \\ = \left(-\frac{1}{3}\right)+\left( \frac{28}{40}\right)+(-2) = \left(-\frac{1}{3}\right)+\left( \frac{7}{10}\right)+(-2) \\ =\left( \frac{-10+21}{30}\right) +(-2) =\left( \frac{11}{30}\right) +(-2) = \frac{11-60}{30} =-\frac{49}{30}.$
