Adding and subtracting mixed numbers is similar to adding and subtracting fractions.
Adding and subtracting mixed numbers with like denominators:
1) 5 3/7 + 6 2/7= 11 5/7
a) add the fractions: 3/7 + 2/7 = 5/7
b) add the whole numbers: 5 + 6 = 11
2) 12 3/8 - 2 1/8
a) subtract the fractions and simplify if it is possible: 3/8 - 1/8 = 2/8 = 1/4
b) subtract the whole numbers: 12 - 2 = 10
Adding and subtracting mixed numbers with unlike denominators:
1) 2 3/2 + 5 4/3 = 9 5/6
a) write the fractions as equivalent fractions with a common denominator:
3/2 = (3 x 3)/(2 x 3) = 9/6 and 4/3 = (4 x 2)/(3 x 2) = 8/6
b) add the fractions: 9/6 + 8/6 = 17/6
c) add the whole numbers: 2 + 5 = 7
d) simplify: 7 17/6 = 9 5/6 (since 2 x 6 = 12, and 17 - 12 = 5, then 7 + 2 = 9)
2) 7 1/5 - 5 2/3 = 1 8/15
a) Since 1/5 < 2/3, we borrow 1 (which represents 5/5) form the whole number 7, so we have 6 as a whole number and the fraction 1/5 become:1/5 + 5/5 = 6/5. Now we can subtract as:
6 6/5 - 5 2/3 = 1 8/15
b) write the fractions as equivalent fractions with a common denominator:
6/5 = (6 x 3)/(5 x 3) = 18/15 and 2/3 = (2 x 5)/(3 x 5) = 10/15
b) subtract the fractions: 18/15 - 10/15 = 8/15
c) subtract the whole numbers: 6 - 5 = 1

Do you change a mixed number into an improper number while adding and subtracting?
you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions
How is adding mixed numbers different from adding fractions?
when you add mixed numbers you have a whole number but adding fraction does not.
What does subtracting mixed numbers mean?
