Answer: c
Step-by-step explanation: I added each one to see if it was equivalent the answer to the problem is 7 8/12 i got that by
7 + 5/6 + 4/3 finding the least common denominators
5/6 = 10/12
3/4 = 9/12 so the LCD is 12
10/12 + 9/12 = 19/12
19 divided by 12 equals 1 with a remainder of 7
19/12 = 1 7/12
7 + 1 + 7/12 = 8 7/12
