Whats the least common demominator of 12,11,and 5

660

Step-by-step explanation: To find the LCM or least common denominator, you have to find the prime numbers that all the numbers share. In this example, these numbers would be 2, 3, 5, and 11. However, 2 appears twice, therefore, when multiplying you must do 2*2*3*5*11 to get 660. hope that helps!

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

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
