1. Mario has 12 boxes of pizza. He cut each pizza into eights. How many pieces of pizza will there be? 2. Tony had 5 1/2 kilograms of sugar. How many cakes can he take if he will use 1/4 kilogram of sugar per cake?

3. What is the average 2 1/4 and ? 3 1/3

4. Jay will put 4/5 mg of salt in each plastic. How many plastics will he need for 14 mg of salt?

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

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
