# What is 0.4 divided by 8?

Mar 10, 2018

$\setminus \frac{1}{20}$ 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 $\setminus \frac{2}{5}$.

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

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 $\setminus \frac{8}{1}$, which is equivalent to $8$.

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