Question

Divide 10 by 4and then subtract 6.2

Answer 1

$10 : 4 - 6,2$    sharing takes precedence

$\frac{10}{1} : \frac{4}{1} - 6 \frac{2}{10} = \\ \\ \frac{10}{1} * \frac{1}{4} - 6 \frac{2}{10} = \\ \\ \frac{5}{1} * \frac{1}{2} - 6 \frac{2}{10} = \\ \\ \frac{5}{2} -6 \frac{2}{10} = \\ \\ 2 \frac{1}{2} - 6 \frac{2}{10} = \\ \\ 2 \frac{5}{10} - 6 \frac{2}{10} = \\ \\ 2 \frac{5}{10} - 2 \frac{5}{10} - 3 \frac{7}{10} = -3 \frac{7}{10}$
