What is 4 2/3 - 1 4/5 =

43/15

Step-by-step explanation:

4 2/3 -1 4/5

Change the fraction to improper fraction

14/3-9/5

The LCM of 3 and 5 is 15

70-27 over 15

=43/15

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
