Question

(-1/9-1/3)+(1/4-2/3).2/5

Answer 1

$( - \frac{1}{9} - \frac{1}{3} ) + ( \frac{1}{4} - \frac{2}{3} ) \times \frac{2}{5} =$

$( - \frac{1}{9} - \frac{1}{3} ) + ( \frac{3 - 8}{12} ) \times \frac{2}{5} =$

$( \frac{ - 1 - 3}{9} ) + ( - \frac{5}{12} ) \times \frac{2}{5} =$

$- \frac{4}{9} - \frac{5}{12} \times \frac{2}{5} =$

$- \frac{4}{9} - \frac{10}{60} =$

$- \frac{4}{9} - \frac{10( \div 10)}{60( \div 10)} =$

$- \frac{4}{9} - \frac{1}{6} =$

$\frac{ - 8 - 3}{18} =$

$- \frac{11}{18} = - 0.61$
