[tex] \frac{2}{9} + 0.5 - 0.1 \div \frac{1}{7} \\ = \frac{2}{9} + \frac{5}{10} - \frac{1}{10} \times \frac{7}{1} \\ = \frac{2}{9} + \frac{5}{10} - \frac{7}{10} \\ = \frac{10 \times 2 + 9 \times 5 - 9 \times 7}{90} \\ = \frac{20 + 45 - 63}{90} \\ = \frac{65 - 63}{90} \\ = \frac{2}{90} \\ = \frac{2 \div 2}{90 \div 2} \\ = \frac{1}{45} [/tex]

Maaf Kalau Salah
