If you want to add or subtract fractions and mixed numbers you have to convert the mixed number to an improper fraction. Then you need to find a common denominator for both fractions. You can then perform the operation.
For example:
If you want to add 3/4 and 10 2/3, you have to first convert the 10 2/3 to an improper fraction, which is 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 = 137/12; convert 137/12 to a mixed number by dividing 137 by 12, which is 11 with a remainder of 5; 137/12 becomes 11 5/12.

multiply the denominator by the whole number then add the numerator and you have an improper fraction
How to add mixed fractions?
you can't add nor subtract mixed fractions so you need to turn it into a fraction, if you wanna turn a mixed fraction into a fraction you need to multiply the whole number by the denominator, then add the numerator, then you can multiply normally (make sure you simplify and turn it into a mixed fraction your answer)
What is the number containing a whole number and a fraction?
A mixed number
