First you would knock out the zeros
20,400-> 20,40 10-> 1
Then divide like normal
2040 divided by 1 equals 2,040
First you need to find a common denominator which in this case is 6. knowing this you fractions would now be 5/6 or a carat and 2/6 of a carat.
5/6-2/6=3/6.
3/6 is equal to 1/2 so if you need to find the simplest form. Hope this helps!
