Hey! i would really appreciate it if you could answer this question. you for your ! 4.8/ 16/9=1.2b/ 20/3b= ?

the answer is 4.8/16/9=(1.2b)/20/3

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

i think the answer is b.

step-by-step explanation:

not 100% sure though.
