Let's put these into decimals to make it easier.
8 1/4 = 8.25, and 3 2/5 = 3.40
Now that we have them in decimal form we can add them.
8.25 + 3.40 = 11.65, or 11 13/20.
I hope this helps!

8 1/4 + 3 2/5

Multiply 8 1/4 by 5/5 so that it has a denominator of 20.

Multiply 3 2/5 by 4/4 so that it has a denominator of 20.

8 1/4 × 5/5 = ?

Turn 8 1/4 into an improper fraction.

(4 × 8) + 1 = 33/4

So, 33/4 × 5/5 = 165/20

Turn 3 2/5 into an improper fraction.

(5 × 3) + 2 = 17/5

17/5 ×4/4 = 68/20

So, our new question is : 165/20 + 68/20

Because they have the same denominator, all you have to do is add the numerators together, and leave the denominator alone.

165 + 68 = 233

So, our answer is 233/20

However, we must turn this into a mixed number.

11 13/20
