You can just use the site calculator for this. It is on the 'home' page.

Do you need to know how to do it by hand?

First, you change the decimal 0.04 into 4/1,000.

Then, you change 12 into a fraction. 12=12/1

After that, do the reciprocal for 4/1,000. 4/1,000=1,000/4

Then, you multiply 12/1 by 1,000/4.

So, the answer is 1/300. Hope it helps, Melody.

Hi Dragon Slayer,

Let's look at this

First, you change the decimal 0.04 into 4/1,000. Wrong

Then, you change 12 into a fraction. 12=12/1 Correct

After that, do the reciprocal for 4/1,000. 4/1,000=1,000/4 No, you don't do that.

Then, you multiply 12/1 by 1,000/4. No

So, the answer is 1/300. Sorry but 12/1*1000/4=3000

Hope it helps, Melody. Nope didn't help

Question: 0.04/12

Hi Dragon Slayer, If you are going to do it using fractions this is how it is done.

Let's look at this

0.04 = 4/100

Then, you change 12 into a fraction. 12=12/1 Correct

It is the second one you turn upside down. To divide by 12/1 you multiply by 1/12

$$\mathbf{\textcolor[rgb]{0,0,1}{\frac{4}{100}\times \frac{1}{12}=\frac{4}{1200}=\frac{1}{300}}}$$

--------------------------------------------------------------------

Maybe it is easier to do it with decimals

$$\frac{0.04}{12}\\\\

=\frac{0.04\div 4}{12\div 4}\\\\

=\frac{0.01}{3}\\\\

=\frac{0.01\times 100}{3\times 100}\\\\

=\frac{1}{300}\\\\$$ $$OR\\\\

\begin{array}{rl}

&\;0.00333333\\

3&\overline{|0.010000}\\\\

\\\\\\\\\\

\end{array}$$
