Question

Simplify (2-¹÷5+²)×(-6/8)-¹​

Answer 1

Answer:

$( {2}^{ - 1} \div 5 + 2)( \frac{ - 6}{8} {)}^{ - 1} \\ = ( \frac{1}{2} \times \frac{1}{5} + 2)( \frac{ - 8}{6}) \\ = (\frac{1}{10} + 2)( \frac{ - 8}{6} ) \\ =( \frac{1 + 20}{10} )( \frac{ - 8}{6} ) \\ = \frac{21}{10} \times \frac{ - 8}{6} \\ = \frac{7 \times - 2}{5} \\ = \frac{ - 14}{5}$
