How do you divide #.12# by #8#?

Answer 1

Riley Anderson

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#

To divide 0.12 by 8, you can first multiply both the numerator and denominator by 100 to eliminate the decimal point. This gives you 12 divided by 800. Then, divide 12 by 800, which equals 0.015. Therefore, 0.12 divided by 8 equals 0.015.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
