#0.4 = 4/10 =2/5#

The first decimal place after the point represents the place holder 'tenths'.

#0.4 = 4/10#

This can simplify to #2/5#

#4/10# or #2/5#

Dividing #4# by #10# (or #2# by #5#) will yield #0.4#, meaning that all you have to do is write out the division problem as a fraction, like this.

#4/10#

Simplifying this fraction by dividing both the numerator and denominator by #2# will yield the fraction #2/5#, which also equals #0.4#.
