    Think about it this way: 0.4 is read as what?

    It's read as "four tenths".

    This means that it can also be said as "four out of ten".

    So, 0.4 into a fraction is "4/10".

    Now, this fraction can be reduced, so what is the greatest common factor of 4 and 10?

    Factors of 4: 1,2,4

    Factors of 10: 1,2,5,10

    So the greatest common factor is 2.

    So, if you divide both 4 and 10 by the greatest common factor to get (4/2) = 2 and (10/2) = 5.

    So, the reduced fraction would end up being 2/5.

    When you divide 2 by 5, you get 0.4, if you want to check.
