Yes.
If one matrix is p*q and another is r*s then they can be multiplied if and only if q = r and, in that case, the result is a p*s matrix.
That is called the identity matrix. For example, (3,1,4)t x (1,1,1) = (3,1,4)t In this case (1,1,1) is the identity matrix. Another example is 5 11 1 0 1 11 x = 4 3 0 1 4 3 (You will have to imagine the brackets around the matrices as I did not know how to draw them in.) In this case 1 0 is the identity matrix. 0 1
((3 over 4) multiplied by 2) over 3 = 0.5
1/2
For example, if you have [ -4 1 0 3] as your matrix, it would be negative 4. Whatever negative number is in your matrix is your answer.
1/4 × 1/3 = (1×1)/(3×4) = 1/12

4/3 or (1 and 1/3)
3 multiplied by 5/4 is equal to 15/4.
4 × 1/3 = 1 and one third, or 4/3.
