A can contains 1/2 pint of paint. If we use 2/3 of the paint, how much paint is left in the can? A. 1/2

B. 1/3

C. 2/3

D. 1/6

E. 5/6

d

Step-by-step explanation:

Quantity of paint used = (2/3) of (1/2)

Quantity left in the can =

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
