The product is

Step-by-step explanation:

Start with:

is the same as .

Let's rewrite:

Distribute in to :

And distributed in to is the same as ×

Multiply.

×

Now let's add our new whole number and fraction.

And we've already established that the expression above is how we can rewrite a mixed number, so let's make it a mixed number by adding.

.

step-by-step explanation:

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
