See a solution process below:

We can write $0.12 -: 8$ as $0.12/8$

Next, we can multiply this by the appropriate form of $1$ to eliminate the decimal:

$10/100 xx 0.12/8 => (100 xx 0.12)/(100 xx 8) => 12/800$

We can now factor this and eliminate common terms giving:

$12/800 => (4 xx 3)/(4 xx 200) => (color(red)(cancel(color(black)(4))) xx 3)/(color(red)(cancel(color(black)(4))) xx 200) => 3/200$

We can now multiply this by another form of $1$ giving:

$5/5 xx 3/200 => (5 xx 3)/(5 xx 200) => 15/1000$

15 thousandths can be written as: $0.015$
