(9*5/12-16/25)*(11/6*0.9-7/4)​

Answer 1

$(9 * \frac{5}{12} - \frac{16}{25}) * (\frac{11}{6} * 0,9 - \frac{7}{4}) =$

1) $9 * \frac{5}{12} = \frac{15}{4} = 3,75$

2) $\frac{375}{100} - \frac{16}{25} = \frac{375}{100} - \frac{64}{100} = \frac{311}{100}$  

3) $\frac{11}{6} * \frac{9}{10} = \frac{33}{20}$

4) $\frac{33}{20} - \frac{7}{4} = \frac{33}{20} - \frac{35}{20} = -\frac{2}{20}$

5) $\frac{311}{100} * (-\frac{2}{20}) = \frac{311}{100} * (-\frac{10}{100}) = -31,1$
