Question

((1/3*2.5-7/8):5/12)-1 1/4​

Answer 1

$((\frac{1}{3} * \frac{25}{10} - \frac{7}{8}) : \frac{5}{12}) - \frac{5}{4} = -1,35$

1) $\frac{1}{3} * \frac{25}{10} = \frac{25}{30} = \frac{5}{6}$

2) $\frac{5}{6} - \frac{7}{8} = \frac{20}{24} - \frac{21}{24} = -\frac{1}{24}$

3) $-\frac{1}{24} : \frac{5}{12} = -\frac{1}{24} * \frac{12}{5} = -\frac{1}{10}$

4) $-\frac{1}{10} - \frac{5}{4} = -\frac{2}{20} - \frac{25}{20} = -\frac{27}{20} = -1,35$
