Answer:

Both are correct.

A) A decimal fraction

B) A common fraction

Step-by-step explanation:

1 step. Write down 0.4 divided by 1:

$\dfrac{0.4}{1}.$

2 step. Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):

$\dfrac{0.4}{1}=\dfrac{0.4\cdot 10}{1\cdot 10}=\dfrac{4}{10}.$

This fraction is called a decimal fraction.

3 step. Simplify the decimal fraction:

$\dfrac{4}{10}=\dfrac{2\cdot 2}{2\cdot 5}=\dfrac{2}{5}.$

This fraction is called a common fraction.
