[tex]2.5 \% \div \frac{ 1 }{ 4 } - \frac{ 11 }{ 5 } \times 20 \% \\ =\frac{2.5\times 4}{100}-\frac{11}{5}\times \left(\frac{20}{100}\right) \\ = \frac{10}{100}-\frac{11}{5}\times \left(\frac{20}{100}\right) \\ = \frac{1}{10}-\frac{11}{5}\times \left(\frac{20}{100}\right) \\ = \frac{1}{10}-\frac{11}{5}\times \left(\frac{1}{5}\right) \\ = \frac{1}{10}-\frac{11}{25} \\ = \frac{5}{50}-\frac{22}{50} \\ = -\frac{17}{50} [/tex]
