Salut!

$( - \dfrac{1}{125} ) \div 0.008 + 0.(7) + 0.(3)^{2} = \\ \\ ( - \dfrac{1}{125} ) \div \dfrac{8}{1000} ^{(8} + \dfrac{7}{9} + ( \dfrac{3}{9} ^{(3} ) ^{2} = \\ \\ ( - \dfrac{1}{125} ) \div \dfrac{1}{125} + \dfrac{7}{9} + ( \dfrac{1}{3})^{2} = \\ \\ - \dfrac{125}{125} ^{(125} + \dfrac{7}{9} + \dfrac{ {1}^{2} }{ {3}^{2} } = \\ \\ - 1 + \dfrac{7}{9} + \dfrac{1}{9} = \\ \\ ^{9)} - 1 + \dfrac{8}{9} = \\ \\ - \dfrac{9}{9} + \dfrac{8}{9} = - \dfrac{ 1}{9}$
