Question

(2\5)-2-(1\4)-1+((-1\6)-2

Answer 1

$\frac{2}{5} -2- \frac{1}{4} -1+ \frac{1}{6} -2=\frac{24}{60}-\frac{120}{60}-\frac{15}{60}-\frac{60}{60}+\frac{10}{60}-\frac{120}{60}\\ \\=\frac{24-120-15-60+10-120}{60}=-\frac{281}{60}$
$\ \ \ \frac{2}{5} -2- \frac{1}{4} -1+ (-\frac{1}{6}) -2\\ \\=\frac{2}{5} -2- \frac{1}{4} -1-\frac{1}{6} -2\\ \\=\frac{24}{60}-\frac{120}{60}-\frac{15}{60}-\frac{60}{60}-\frac{10}{60}-\frac{120}{60}\\ \\=\frac{24-120-15-60-10-120}{60}\\ \\=-\frac{301}{60}$
