Resposta:
[tex] \frac{21079}{4200} [/tex]
Explicação passo-a-passo:
[tex]0.24 = \frac{6}{25} \\ \\ 0.42 = \frac{21}{50} [/tex]
[tex] \frac{6}{25} \times \frac{33}{16} + \frac{19}{10} \div \frac{21}{50} [/tex]
[tex] \frac{3}{25} \times \frac{33}{8} + \frac{19}{10} \times \frac{50}{21} \\ \\ \frac{99}{200} + 19 \times \frac{5}{21} \\ \\ \frac{99}{200} + \frac{95}{21} = \frac{21079}{4200} [/tex]
