Multiply the amount by 1000 to remove the decimal point (this becomes the number on top of the fraction; the numerator) = 821. Divide this new number by the amount you just multiplied by to express the original amount (this is the number on the bottom; the denominator) = 1000. Thus we write 0.821 as 821/1000. (Note: This can not be simplified any further as 821 is both a prime number and does not divide into 1000 to provide an integer as a result.)
