Opera y simplifica: 19/36:5/4-11/20​

Answer 1

Respuesta:

$\frac{19}{36} \div \frac{5}{4} - \frac{11}{20} \\ \\ \frac{19}{36} \times \frac{4}{5} - \frac{11}{20} \\ \\ \frac{19}{ \cancel{36} \: _9 } \times \frac{ \not4 {}^{1} }{5} - \frac{11}{20} \\ \\ \frac{19 \times 1}{9\times 5} - \frac{11}{20} \\ \\ \frac{19}{45} - \frac{11}{20} \\ \\ \frac{76 - 99}{180} \\ \\ - \frac{23}{180}$
