Answer:
The answer is 15 21/40
Step-by-step explanation:
If you convert 8 1/8 to 8 5/40 then convert
7 2/5 to 7 16/40 then add the wholes 7 + 8 = 15
and then add the actual fractions 5/40 + 16/40 = 21/40
then add the whole and the fraction 15 + 21/40 youll end
up with 15 21/40 so that is the awnser PS I’m in 5th grade age 10
