Will pick brainiest answer and u have to be my friend what is 5 1/3 + 4 2/5

The answer is 146/15.

Change the mixed numbers from mixed numbers into fractions, so you would have:
16/3 + 22/5
Now to add these two together, they have to have the same denominator. To do that, multiply 16/3*5/5 and 22/5*3/3 and your new terms would be:
80/15 + 66/15
Now you can add the numerators together:
146/15
and simplify for your
9 11/15
