Elisa has 24 black and white photographs and 72 photographs in color. She is arranging the photographs in an album and wants each page to contain the same combination of color and black and white photographs. What is the greatest number of pages that Elisa can fill with photographs? and how many of each type of pohotograph will elisa place on each album page without any photographs being left over ?

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

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
