[tex]h( - 2 \frac{1}{9}) \div 0.(7) \div ( - \frac{38}{49}) \\ = h( - \frac{19}{9}) \div \frac{7}{9} \div ( - \frac{38}{49}) \\ = - h(\frac{19}{9}) \times \frac{9}{7} \div ( - \frac{38}{49}) \\ = - \frac{19h}{7} \times ( - \frac{49}{38}) \\ = - \frac{19h}{7} \times ( - \frac{7 \times 7}{2 \times 19} ) \\ = \frac{7h}{2} [/tex]
