To turn an improper fraction [16/6] into a mixed fraction, you must divide 16 over 6, then turn the remainder into a fraction.
Lets begin!
1) Find how many times 6 goes into 16 evenly (Twice {This equals 12})
2) Subtract 12 from 16 to find the remainder (16-12=4)
3) Use the remainder to form a fraction (4/6)
4) (Optional) Simplify the remainder if needed (2/3 {Most teachers may prefer this way, so its a good habit to get into :)}
5) Form the entire fraction (2 2/3)
Hope this helped in any way!
