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

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