to write 0.4 in Fraction form look all the way to the right is the last digit is in the tenths place then you know your denominator will be 10 and since the 4 is in tenths place your numerator will be 4
So 4/10 and this can be simplified
To do this find a number that will go into four and 10 evenly 2 will go into both of those evenly
So you would start with the numerator 4/2=2 so the numerator is 2 now do the denominator 10÷2=5 so you're denominator will be 5
So 2/5 is the answer.
