The easiest way is to just find a common denominator. You will have to first turn your mixed fraction into an improper fraction.
For example
8/7 and 1 and 2/7 is an example of an improper fraction and a mixed fraction.
think of 1 and 7/7 and add it to 2/7 so 1 and 2/7 is 9/7. Now add 9 and 8 and the answer is 17/7.
In some cases, you will need to find a common denominator after changing the mixed fraction into an improper one.
3/2 and 1 and 2/5 is an example
1 and 2/5 is 7/5 and to add fifths and halves you need a common denominator of 10
So 3/2 is 15/10 and 7/5 is 14/10, now add them and you have 14+15 =29/10

How do you add a mixed number and an improper fraction?
I wouldconvert both to improper fraction,find a common multiple (CM),calculate equivalent fraction with CM as the denominator,add the numerators,change the improper fraction to a mixed fraction, if required,simplify the fractional part of the mixed fraction - if appropriate and required.
How do you turn a mixed fraction to an improper fraction?
multiply the denominator by the whole number then add the numerator and you have an improper fraction
How do you add mixed proper and improper fractions?
It is best to convert the mixed fraction to an improper fraction. They are then added together in the same way as proper fractions are added together.
How do you add a mixed fraction by a mixed fraction?
You can either add the fractional parts and, if required, convert the answer to a mixed fraction and then add the integer part to the integer parts of the two original numbers; or change both numbers to top-heavy (or improper) fractions, add them and then convert the answer to a mixed fraction.
How do you write a mixed number as an equivalent fraction?
To convert a mixed number to an improper fraction, multiply whole number part by the denominator of the fraction part, then add the numerator to the product. The result is the numerator of the improper fraction. The denominator remains the same. For example, to convert 2 3/8 to an improper fraction, multiply 2*8 = 16, then add 3 to get 19. The improper fraction is 19/8.
