say you were given the fraction 21/4. first, see how many times 4 goes into 21, which in this case 4 goes into 21, 5 times. (4x5=20) then you would subtract 20 from 21 ; 21-20=1. your answer would be 5 & 1/4.

To change an inproper fraction to a decimal you divide the denominator by the numeratorand once you do that and you find your decimal you bring it over two times to the right.
