option D
2x4; -11
Step-by-step explanation:
Order of matrix is in form (m x n), here m is the row and n is the column of the matrix.
So this matrix have 2 rows and 4 columns
1)Order of matrix
2x4
2)
here 1 is the row and 2 is the column
-11
Each elements of the matrix can be identity as below
![\left[\begin{array}{cccc}x_{11} &x_{12} &x_{13} &x_{14} \\x_{21} &x_{22} &x_{23} &x_{24} \\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7Dx_%7B11%7D%20%26x_%7B12%7D%20%26x_%7B13%7D%20%26x_%7B14%7D%20%5C%5Cx_%7B21%7D%20%26x_%7B22%7D%20%26x_%7B23%7D%20%26x_%7B24%7D%20%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Answer:
2/3
Step-by-step explanation:
1 1/6 - 1/2
Get a common denominator of 6
1 1/6 - 1/2*3/3
1 1/6 - 3/6
Borrow 1 from the 1 in the form of 6/6
6/6 + 1/6 - 3/6
7/6 - 3/6
4/6
Reduce by dividing the top and bottom by 2
2/3
