2)116+83=96.
The answer is A
a. first you subtract 11 from 15 to get 4
b. then you find the LCM of 12 and 8 which is 24
c. divide 24 by 12 and multiply by 5=10
d. divide 24 by 8 and multiply by 1=3
e. subtract your answer in d. from c. = 10-3=7
your answer in e over your LCM
your final answer =option A
