#8 1/6#

Explanation:

It is not necessary to change to improper fractions for adding and subtracting fractions. It often makes the numerators very large.
Just work with the whole numbers separately

#4 7/10+3 7/15#

#= 7 (21+14)/30#

#= 7 35/30#

#= 7 + 1 5/30#

#8 1/6#

Answer in the same format as the question was given.
