Question

How to add these mixed numbers

Answer 1

Make them into improper fractions
(5*5)+3
(2*3)+2

Final fractions
28/5+8/3
Find a common denominator
Multiply 28/5 by 3
84/15
Multiply 8/3 by 5
40/15

Add - 84+40=124

Answer 2

I would rewrite them:
5 3/5 is the same as 18/5
2 2/3 is the same as 8/3

To add them you get the same denominator by multiplying the first fraction by 3 and the second by 5 for a denominator of 15

54/15+40/15
=94/15 or 6 4/15

Hope this helps!
