What is 8 1/3 - 6 2/3

First, you need to take out 3/3 from 8 1/3 because you don't want a negative number. So the 8 becomes 7 and you add 3/3 to 1/3 to get 4/3.
7 4/3-6 2/3
Then, you just subtract.
1 2/3

First, make both mixed numbers into improper fractions.
8 1/3 = 25/3 and 6 2/3 = 20/3
Since you have a common denominator, all you have to do is subract the numerators, so 25/3 - 20/3 = 5/3
You can keep it in improper fraction form, or go back to a mixed number.
5/3 = 1 2/3
