Add. write each sum in simplest form 2 4/5 + 4 1/10

Ok I almost have the answer. Do you want me to explain how I did it?

6 9/10

First make 4/5 to 8/10 by making common denominator which is times 2 and multiply 4 by 2 for numerator. Now just add. 2 8/10 + 4 1/10. You first add 2+4=6. Then, add 8/10+1/10=9/10. Lastly, just put them together which is 6 9/10. That is the simplest form.
