Question

1)-2/0,03-11 2/3/(-1) 2)(4,5-5 5/6)*(4,5/0,1) 3) (-1 1/3)*(-1 1/3)/(-0,8)+2 7/9*(-1)

Answer 1

1)

$- 2 \div 0.03 - 11 \frac{2}{3} \div ( - 1) = - 2 \times \frac{3}{100} - \frac{35}{3} \div ( - 1) = \frac{200}{3} + \frac{35}{3} = - 55$

2)

$(4.5 - 5 \frac{5}{6} )(4.5 \div 0.1) = ( \frac{9}{2} - \frac{35}{6} )45 = - \frac{4}{3} \times 45 = - 4 \times 15 = - 60$

3)

$(- 1 \frac{1}{3} )( - 1 \frac{1}{3} ) \div ( - 0.8) + 2 \frac{7}{9} ( - 1) = - \frac{20}{9} - \frac{25}{9} = - 5$
