$\frac{ - 3 \frac{1}{25} \div 0.04 - 3.61 \times ( - 2 \frac{2}{19}) + 25 }{2.8} = - 15.5 \\ 1) \: - 3 \frac{1}{25} \div 0.04 = - \frac{76 \times 25}{25} = - 76 \\ 2) \: - 3.61 \times ( - 2 \frac{2}{19} ) = \frac{361 \times 40}{100 \times 19} = \frac{19 \times 2}{5} = 7.6 \\ 3) \: - 76 + 7.6 + 25 = - 76 + 32.6 = - 43.4 \\ 4) \: - 43.4 \div 2.8 = - 15.5$
