what do you do with the mixed fraction? Do you turn it into an improper fraction?

Easiest way is to change the whole number- make it 15 8/8ths and subtract to get 7 5/8ths.

you can turn it into a mixed fraction or you can take only part of the whole number as needed (sort of like borrowing)
using your problem, we could do it like this:
16 - 8 3/8 =
[(16*8) - (8*8+3)]/8 = and you can work that out the rest of the way
or (in excruciating detail)
16 - 8 3/8 =
16-8-3/8=
8-3/8 =
7+1-3/8 =
7+8/8-3/3
7+(8-3)/8 =
7 5/8
(you should be able to do all those steps in your head quicker than you can write just the problem)

You turn the fraction into a decimal.
So it the question is 5 - 4 1/4
Turn it into 5-4.25
Or in the case of your question, put the 16 over 1, make the mixed into an improper and find a common demonimator

Change 16 into a fraction, which is 16/1.
Then change 8 3/8 into an improper fraction:
8 x 8= 64. 64+3=67.
so its 67/8
so now you do 16 minus 67/8.

You turn the 16 into a fraction like 16 over 1 then you find a common denominator.

borrow from the 16 to make it 15 and you will have 8/8 as another fraction. 16-8 8/8-3/8=?

Turn a one into 8/8 (or whatever denominator you need, remember that they must be the same to subtract or add)
and subtract the fractions and then the #s
