Answer:
B. 5 11/12
Step-by-step explanation:
Simplify the following:
1 + 7/12 + 4 + 1/3
Put 1 + 7/12 + 4 + 1/3 over the common denominator 12. 1 + 7/12 + 4 + 1/3 = 12/12 + 7/12 + (12×4)/12 + 4/12:
12/12 + 7/12 + (12×4)/12 + 4/12
12×4 = 48:
12/12 + 7/12 + 48/12 + 4/12
12/12 + 7/12 + 48/12 + 4/12 = (12 + 7 + 48 + 4)/12:
(12 + 7 + 48 + 4)/12

Answer: 71/12 = Convert to a mixed number:
71/12
Divide 71 by 12:
1 | 2 | 7 | 1
12 goes into 71 at most 5 times:
| | | 5
1 | 2 | 7 | 1
| - | 6 | 0
| | 1 | 1
Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | | 5 | (quotient)
1 | 2 | 7 | 1 |
| - | 6 | 0 |
| | 1 | 1 | (remainder)
The quotient of 71/12 is 5 with remainder 11, so:
Answer: 5 11/12
