$-12/5" "->" "-2 2/5$

$color(blue)("Do not forget about the minus sign")$

Write as: $" "-4.8/4$

$color(green)([-4.8/4color(red)(xx1)] " "->" "[-4.8/4color(red)(xx10/10)]" " =" " -48/40$

$-(48-:2)/(40-:2)" " =" " -24/10" "=" "-(24-:2)/(10-:2)" "=" "-12/5$

$= -2 2/5$

~~~~~~~~~~~~~~~~~~~~~~~~~
Check:

$4.8-:4 = 1.2$

$12-:5 = 1.2$
