[tex]23 \frac{1}{2} + 18 \frac{26}{100} - (25 \frac{7}{10} \times 2 \frac{6}{10} ) \\ = 23 \frac{1}{2} + 18 \frac{26}{100} - ( \frac{257}{10} \times \frac{26}{10} ) \\ = 23 \frac{1}{2} + 18 \frac{26}{100} - \frac{6,682}{100} \\ = ( \frac{47}{2} + \frac{1826}{100}) - \frac{6.682}{100} \\ =( \frac{2350}{100} + \frac{1826}{100} ) - \frac{6682}{100} \\ = \frac{4176}{100} - \frac{6682}{100} \\ = \frac{ - 2506}{100} [/tex]
