Question

Найди значения выражений: (-33/35: 6/7+7/36: (-5/6))×1,2; 55,08×17/18/3,06

Answer 1

№1
1)$- \frac{33}{35} : \frac{7}{6} = -\frac{33}{30} = -\frac{11}{10} = -1.1$
2)$\frac{7}{36} : -\frac{6}{5} = -\frac{7}{30}$
3)$-\frac{11}{10} + (-\frac{7}{30} )= -\frac{330}{30} + (-\frac{7}{30})= -\frac{337}{30}$
4)$-\frac{337}{30} * \frac{12}{10} = -\frac{4044}{300} = 13.48$
ответ: 13,48

№2
1)$\frac{17}{18} : \frac{100}{306} = \frac{100}{324}$
2)$\frac{558}{100} * \frac{100}{324} = \frac{558}{324}= 1 \frac{234}{324} ≈ 1,72$
