Question

(-1 целая 1/4) + 3,6* 1 целую 5/6

Answer 1

$- 1 \frac{1}{4} + 3.6 \times 1 \frac{5}{6} = - \frac{5}{4} + \frac{36}{10} \times \frac{11}{6} = - \frac{5}{4} + \frac{6 \times 6 \times 11}{2 \times 5 \times 6} = - \frac{5}{4} + \frac{33}{5} = - \frac{25}{20} + \frac{132}{20} = \frac{107}{20} = 5 \frac{7}{20}$

Answer 2

$- 1 \frac{1}{4} + 3.6 \times 1 \frac{5}{6} = - 1 \frac{1}{4} + \frac{36}{10} \times \frac{11}{6} = - 1 \frac{1}{4} + \frac{6 \times 11}{10} = - 1 \frac{1}{4} + \frac{3 \times 11}{5} = - 1 \frac{1}{4} + \frac{33}{5} = - 1 \frac{1}{4} + 6 \frac{3}{5} = 5 \frac{12 - 5}{20} = 5 \frac{7}{20}$
