16/10 as a mixed number would be {1 6/10} or {1 3/5}. First, you figure out how many times the denominator fits into the numerator. So you see how many times ten fits into 16 (the answer would be 1) and that's your whole number. Then, you subtract the denominator from the numerator (16-10) and put our answer (5) as the numerator in the fraction next to the 1 you got in the beginning. Then, all you have to do is simplify.
EXAMPLE:
18/10
how many times does 10 go into 18? once.
1 8/10
1 4/5
