The answer is 2/525

Explanation:

To get from decimals to fractions divide the decimal by the same number of powers of 10 as there are places in the decimal and then simplify the fraction.
There is only one decimal place in 0.4 so divide by 10, which gives you 4/10410; this simplifies by dividing by 2 to get 2/525

If your decimal is something like 0.45 the you get 45/10045100 and this can be divided by 5 to get 9/20920
