You have to convert the mixed fractions to improper fractions and find a common denominator.
For example:
If you want to subtract 3/4 from 10 2/3, you have to first convert the 10 2/3 to an improper fraction, which would be 32/3. Next you have to find the common denominator for both fractions. 3 x 4 = 12, so 12 is the lowest common denominator; therefore, 3/4 = 9/12 and 32/3 = 128/12.
Now you can perform the operation:
128/12 - 9/12 = 117/12; convert 117/12 to a mixed number by dividing 117 by 12, which is 9 with a remainder of 9; 117/12 becomes 9 9/12 or 9 3/4.

How do your borrow from a whole number when subtracting fractions?
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...
