Answer:
10 13/21
Step-by-step explanation:
Convert mixed numbers into improper fractions
4 9/14 --> 65/14
2 6/7 --> 20/7
8 5/6 --> 53/6
Then calculate
65/14 - 20/7 + 53/6
Before that write it into a common denominator of 42
(195-120+371)/42
That would equal to 446/42
Divide it by 2
That would equal to 223/21
Then 223/21 = 10 13/21
