$- \frac{12}{5} \to - 2 \frac{2}{5}$ $-12/5" "->" "-2 2/5$

Explanation:

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

Write as: $- \frac{4.8}{4}$ $" "-4.8/4$

$[- \frac{4.8}{4} \times 1] \to [- \frac{4.8}{4} \times \frac{10}{10}] = - \frac{48}{40}$ $color(green)([-4.8/4color(red)(xx1)] " "->" "[-4.8/4color(red)(xx10/10)]" " =" " -48/40$

$- \frac{48 \div 2}{40 \div 2} = - \frac{24}{10} = - \frac{24 \div 2}{10 \div 2} = - \frac{12}{5}$ $-(48-:2)/(40-:2)" " =" " -24/10" "=" "-(24-:2)/(10-:2)" "=" "-12/5$

$= - 2 \frac{2}{5}$ $= -2 2/5$

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

$4.8 \div 4 = 1.2$ $4.8-:4 = 1.2$

$12 \div 5 = 1.2$ $12-:5 = 1.2$
