multiply the number in front of the fraction on the mixed number by the denominator and add that to the numerator to convert it to an improper fraction, then add
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 you add and subtract mixed numbers?
SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
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...

How do you add and subtract fractions in math?
You need common denominators. Then add or subtract the numerators. If the answer is an improper fraction it is common practice to reduce it to a mixed number.
What are two things you have to think about when you add or subtract mixed numbers that you do not have to consider when you add or subtract fractions?
I believe there is only one difference. The mixed numbers have to be converted to fractions. After that the operation is the same. Each fraction then must have a common denominator in order to add or subtract which is true in either case. Perhaps you need to convert back to mixed number however you might have to do that also when adding fractions. Example 9/16 +9/16 =18/16 = 1 1/4. And in subtracting mixed numbers you might end up with a complete fraction thus not needing conversion. Therefore I see only one definite difference as described above on the first paragraph.
