5 2/5 + 3 1/4

To add 5 2/5 and 3 1/4, we first need to convert the mixed numbers to improper fractions.

5 2/5 = 5 + 2/5 = 25/5 + 2/5 = 27/5
3 1/4 = 3 + 1/4 = 12/4 + 1/4 = 13/4

Now we can add the fractions:

27/5 + 13/4

To add these fractions, find a common denominator which in this case is 20:

27/5 = (27/5) * (4/4) = 108/20
13/4 = (13/4) * (5/5) = 65/20

Now we can add the fractions:

108/20 + 65/20 = 173/20

Finally, we can convert the result back to a mixed number:

173/20 = 8 13/20

Therefore, 5 2/5 + 3 1/4 = 8 13/20.
