(-11,75: (-2,6)-1,8) ·(-7): (-0,2)

Answer 1

$( - 11.75 \div ( - 2.6) - 1.8) \times ( - 7) \div ( - 0.2) =95 \frac{9}{52} \\ - 11.5 \div ( - 2.6) = \frac{47 \times 5}{4 \times 13} = \frac{235}{52} \\ \frac{235}{52} - 1.8 = \frac{235}{52} - \frac{9}{2} = \frac{1175}{260} - \frac{468}{260} = \frac{707}{260} \\ \frac{707}{260} \times ( - 7) = - \frac{4949}{260} \\ - \frac{4949}{260} \div ( - 0.2) = \frac{4949 \times 5}{260} = \frac{4949}{52} = 95 \frac{2}{52}$
