\frac{1}{20} or 0.05

Explanation:

You can use a calculator to figure out this answer, but it's always good to know how to solve it manually.

I suggest you to convert 0.4 into a fraction -- that would be \frac{2}{5}.

Now you can rewrite the question into \frac{2}{5} \div 8.

Use what you know about dividing with fractions: remember multiply the first fraction with the reciprocal of the second fraction. The number 8 may not look like a fraction to you now, but you can always add a 1 to the denominator to create a fraction \frac{8}{1}, which is equivalent to 8.

\frac{2}{5} \times \frac{1}{8} = \frac{2}{40} = \frac{1}{20} = 0.05
