to convert an improper fraction to mixed, is just a matter of division.
in this case, we divide 19 ÷ 10, that gives us a quotient of 1, and a remainder of 9.
10 out of 10 equals 1.
then there is 9 left.
This gives 1 and 9 over 10.
9 over ten is not a whole number as 10 over ten is.
Hope this helps.
