Answer:
(a). 
= ![\left[\begin{array}{cc}12&-4\\66&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D12%26-4%5C%5C66%266%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
A = ![\left[\begin{array}{cc}5&-4\\3&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D5%26-4%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D)

21 and 7/8-8 and 5/12
remember that 21 and 7/8=21+7/8 and 8 and 5/12=8+5/12 so
21+7/8-(8+5/12)
21+7/8-8-5/12
21-8+7/8-5/12
13+7/8-5/12
so 7/8 and 5/12
make bottom number the same
multiply 7/8 by 12/12 and multiply 5/12 by 8/8
7/8-5/12=84/96-40/96=(84-40)/96=44/96=11/24
so the answer is
13 and 11/24
