To find the difference of 7 - 3 5/12, how do you rename 7?

You would rename 7 as 6 12/12. The answer is 3 7/12.

Step-by-step explanation:

1.)  6 12/12 - 3 5/12

2.) 6 - 3 = 3

3.) 12/12 - 5/12 = 7/12

4.) 3 7/12

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
