k = -10

Step-by-step explanation:

-6/5 = - 1 1/5

Since -6/5 is a negative, you must multiply it with another negative. Or you can put -6/5 as a positive.

First, notice that 1 1/5 would make a whole number (with no fraction) with something in the 5s. 1 times 10 = 10 (-1 times -10 =10) and 1/5 times 10 = 2 (-1/5 times -10 = 2) Finally, put those together to get 12.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
