[tex] \sqrt{2 \frac{7}{9} } \times 3 + \frac{3}{4} \div ( - 1 \frac{1}{2} ) ^{3} = \sqrt{ \frac{25}{9} } \times 3 + \frac{3}{4} \div ( - \frac{3}{2} ) {}^{3} = \frac{5}{3} \times 3 + \frac{3}{4} \div ( - \frac{27}{8} ) = 5 + \frac{3}{4} \times ( - \frac{8}{27} ) = 5 - \frac{2}{9} = 4 \frac{7}{9} [/tex]
