Mrs. Petruzziello’s class is working on a math project. There are 5 groups. Mrs. Petruzziello has 3 packs of construction paper for everyone to share. What fraction of a pack will each group get to use?

1/5

Step-by-step explanation:

1 pack of paper/ 5 groups

or all three groups

3/5

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
